Grandstream UCM6510

Introducing the new Grandstream UCM6510 IP PBX.

What is it?

The Grandstream UCM6510 is a new IP PBX appliance with enterprise grade features that is still targeted for the SMB market.

This IP PBX appliance is similar to Grandstream’s UCM6100 series, but with a much higher user count. The Grandstream UCM6510 is the most robust and feature appliance that Grandstream has released.

The UCM6510 offers a single T1/E1/J1 along with 2 FXO and 2 FXS ports in case of a power outage. Grandstream made this IP PBX appliance come standard with dual gigabit Ethernet ports, a 1 GHz quad-core Cortex A9 application processor along with a customizable auto attendant.

Who is it for?

The UCM6510 has call center and enterprise level features and can also be scaled down and used in a small-to-medium (SMB) setting.

With that in mind, plus the ease of use and set up that Grandstream provides with their appliances makes these units attractive to a large array of businesses and users.

With call features too long list and a price point that one would think it’s a mistake, the Grandstream UCM6510 is a great product for most any type or size of business.


Grandstream UCM6510 IP PBX Appliance – MSRP $1,999

Grandstream UCM6510 IP PBX Appliance Features:

  • 2 FXS and 2 FXO ports with lifeline capability incase of a power outage
  • Single T1/E1/J1 port
  • Ability to handle unlimited SIP accounts
  • Rack mount available
  • Call Center features accessible
  • Up to 2000 registered SIP endpoints and 200 concurrent calls
  • Auto Provision and Detection of end points
  • Redundant power supply

Questions about VoIP devices and services are regularly submitted to VoIPSupply.com through a technical support ticket or via the “Ask The Expert” tab on our product pages.

We respond to these requests directly but more often than not, this Q & A would be helpful for lots of other folks.

Below are your VoIP questions answered – Real questions from real people  just like you.

Plantronics Voyager PRO HD
Plantronics Voyager PRO HD

Q:  I want to use this Wireless headset [Plantronics Voyager PRO HD] with a VOIP system that I plan to install on my iMac… does it only function with a mobile device (phone), or will it work with any desktop/laptop computer as well? Thanks!

The Plantronics Voyager PRO HD is a monaural Bluetooth headset designed to connect to iPhones and Android phones.

However the Voyager PRO HD user guide does say:

If your phone, laptop or tablet PC supports Bluetooth A2DP stereo streaming, you can listen to streaming audio

Technically that sounds like it could work with your Bluetooth enabled laptop or, you might want to pair the headset with the optional Plantronics Voyager PRO HD USB adapter with your laptop or desktop.

Personally I haven’t had the best luck pairing Bluetooth headsets with my Windows 7 laptop – it can never seem to install the correct drivers. My desktop computer at work, on the other hand, has no problems working with Bluetooth and wireless headsets that are connected via the USB adapter.

Then again, you’ll probably have no problems with your iMac. And the USB adapter is a good backup plan if the Bluetooth won’t sync.

Another option is the Plantronics Voyager Legend UC B235 which boasts multi-device connectivity

Another option to consider for connecting to laptops and desktops is the Plantronics Voyager Legend UC B235 which is an advanced Bluetooth headset that comes with a USB Bluetooth dongle – its multi-device connectivity lets you manage PC and mobile/tablet phone calls from a single headset.

Badly Photoshopped VoIP Phones as Spaceships
The Cisco SPA112 in our “Badly Photoshopped VoIP Phones as Spaceships” blog post


Q: Is the Lynksys PAT2T being phased out, and the Cisco SPA112 will be the new product to replace it? I want to make a purchase, but will be reluctant to do so if the Lynksys PAP2T is being replaced.

A:  You’re correct. The Lynksys PAP2T is End of Life – it has been replaced by the Cisco SPA112 VoIP Adapter.

The Lynsys PAP2T, if you can find one, might still work for what you need. But since it is no longer being sold and is no longer supported by Cisco, we recommend going with the SPA112 replacement.


Q:  I am traveling to the US and my parents will remain in Puerto Rico. I want to know if this equipment [Grandstream GXV3140] is recommended for daily contacts with them via SKYPE. They are at a elderly home facility which has internet connection, but i am not sure what i need for this. Please let me know if you recommend this or something else. 

A:  The Grandstream GXV3140 is a Skype certified IP Video that makes it easy to make Skype video calls with its integrated web browser and 4.3in Color LCD screen.

You can make free voice and video calls via Skype on the GXV3140 just by plugging the phone into your network or, internet connection.

Since this phone is Skype certified, Skype comes pre-installed. With this phone you can call any other Skype users whether they’re using a GXV3140 of their own or a webcam, laptop, cell phone, or tablet. You just need the internet or, network connection to make this happen.

The Grandstream GXV3140 is currently in stock but it’s going end of life so you may want to consider it’s replacement, the Grandstream GXV3240.

Grandstream UCM 6100-banner-voip-supply

Door Phone and Door Station Support

Q: Can it [UCM6100] support door phone, control, attendance systems? E.g. Helios 2N, any others?

A:  Yes, it supports door stations. We have verified this against FXS/FXO devices from Viking Electronics as well as 2N.

Q: Can we use this system to open gates or use in a system gate?

A:  Yes, this system can perform door station functions depending on the device being used. We’ve interoped with Viking Electronic devices.

Q: The scenario would be a system with several video-doorphones + one GXV3140 + UCM6102. While one video-call from a video-doorphone is being attended from the GXV3140, there are other video-calls being received from other doorphones and those video-calls should be put on queue. How many calls can be queued?

A:  This would be handled like any other call. Since it is video, it will now have video codec being negotiated. You can configure the call queue based on your own preference.



Q: Because Asterisk is open source, does Grandstream contribute to this effort?

A:  Yes, we comply with GNU/GPL and provide the source details on our FAQ page.

Video Softphones

Q: Any recommended free video softphones for use?

A:  At the moment, we do not have any free apps listed for video calls. It would be suggested to use a softphone that supports h263, h263+, h264.

IVR Security

Q: Standard set of security protocols to avoid hacking, security issues through IVR?

A:  There are several ways of securing the UCM IVR.

1. Password on outbound route
2. Specify permission/privilege level
3. Disable dial trunk option.

Park BLFs and Shared Line Appearances

Q: Are there plans to add Park BLFs or Shared Line Appearances?

A: On the latest firmware for the UCM we support BLF for parking lot. Shared line appearance has already been requested and is taken into consideration for the future release.


Q: Is there a way to install A2Billing?

A: The UCM is a locked down asterisk system so you cannot instlal any applications onto the appliance. however, a later firmware release will support API and allow users to pull caller data for billing programs.

Zero Config

Q: Does the endpoint manager support other vendor phones for configuration and Key defs?

A: No. The UCM can only zero-config Grandstream products at the moment.


Grandstream UCM6102
Grandstream UCM6102

BroadSoft Softswitch

Q: Is the UCM6102 certified to work on BroadSoft softswitch?

A: At the moment, it is stil under certifcation and has not been fully supported. Working in progress.

Voicemail to Email and Remote Voicemail Access

Q: Are we able to listen and delete voicemail directly from Outlook so the voicemail is also deleted in the UCM?

A: No. Voicemail sent to your email needs to be removed from the PBX. It does not sync up with your email. This has been requested for future consideration.

Q: How do you listen to your voice messages remotely, from a phone not registered to the UCM?

A: You can dial into the UCM via IVR, then dial an option for a dummy extension(not registered) and have that dummy extension undconditional forward to your voice mail system *98

Call Monitoring and Recording

Q: Calls Monitor Feature?

A: This has already been requested and is being implemented for a future release. However, we do have an option to record calls.

Q: Can we direct the recordings to external storage?

A: This is done automatcally when a USB/SD is connected to the UCM.

Service Providers Tested

Q: What providers have been successfully tested with this?

A: 3NG, Nexvortex, Callcentric, Clearfly, vitelity, Phonepower.

Google Voice Support

Q: Can google voice be integrated on the UCM?

A: No, this is not supported unless it uses SIP signalling.

Q: Any license fees to use G.729 codec?

A: No licensing fee for G.729, we have a license for the max number of concurrent calls on the UCM.

Grandstream HT704 Adapter

How to Add Additional Analog Phones

Q: How to add FXS phones if i need more analogue phones?

A: All UCM models come with 2 FXS ports. You can add more by using an ATA or FXS gateway like the HT700 series or GXW400x/4200 series.

LAN Ports for Failover

Q: Are the 2 LAN ports in UCM6104 – for a failover mode – i can use 2 separate internet connections? or is there another purpose to the 2 LAN ports?

A: Exactly, this is used for failover purposes.

Demo Programs and Training

Q: If we want to be more familiar with the product do you have some DEMO programs?

A: We do provide UCM trainig events. You can visit this page for all the upcoming events: http://www.grandstream.com/ucm-events

Need More Lines

Q: What I can do if i need more than 16 lines?

A: You can peer an FXO gateway to the UCM. We provide FXO gateways to extend this. Here’s the link to the guide.

T1 or DSL Support

Q: Can we use a T1 or DSL Service?

A: T1/E1 is not supported on the UCM61xx series. However, we are coming out with a UCM65xx series that will support such services.

CounterPath Bria Desktop Client
CounterPath Bria Desktop Client

Desktop Clients

Q: What kind of desktop clients are you supporting? And on what OS?

A: We support either Linux/Mac/Windows. Any soft client that is SIP compliant works with our UCM. E.g CounterPath Bria.

Concurrent Video Calls

Q: Max concurrent video-calls supported?

A: This is anywhere between 6-10 calls.


Q: Does the UCM6100 series use a disk or SSD for storage?

A: Internal flash storage.

Q: Does the USB port of UCM6104 suport a passport drive (which doesn’t have its own power)?

A: That should be fine. I have used a Buffalo 1TB drive without power and was just fine.

System Recovery

Q: I have read that asterisk-based systems have known lock-up issues that typically have to be resolved by a system reboot. How has that been dealt with for this solution?

A: Our system recovers itself during these moments and provide core dump files that can be analyzed by our developers for root cause.

Next generation Grandstream GXP IP Phones, GXP2140 and GXP2160, will be on display at ITEXPO 2014

For the next couple of weeks we’re going to highlight our partners who are exhibiting at ITEXPO Miami 2014 to learn what’s new at this year’s show.

ITEXPO, running from January 28th through January 31st, is a business technology event and tradeshow for VoIP, Unified Communications, Cloud services, phone apps, and more.

3 Questions with Grandstream About ITEXPO

We spoke with Phil Bowers, Global Marketing Communications Manager for Grandstream, about what to expect at this year’s ITEXPO.

VoIP Supply:  For those who aren’t familiar with your company, can you tell us a little bit about Grandstream?

Grandstream:  Grandstream is an award-winning designer and manufacturer of IP Business Solutions. We supply SMBs and Enterprises throughout the world with integrated voice, video, data, and mobility solutions that empower businesses to be more productive while cutting communication costs.

Grandstream offers everything you’ll need for a complete business communications solution: from IP video phones, IP desktop phones, VoIP gateways, and IP video surveillance cameras to IP PBXs (our UCM6100 series IP PBX Appliance).

Our company was found in 2002 and started out manufacturing IP Phones and Analog Telephone Adapters and we have grown into one of the leading IP Solutions company in the world and we now offer a full solutions portfolio of over 50 innovative products.

VS:  What products will you be featuring at this year’s IT EXPO and will you be unveiling anything new?

Grandstream:  We will be showing off our entire solution portfolio at IT Expo. Specifically, In the past few weeks we have released a few really exciting new products that take the Grandstream solution to the next level, and we invite all visitors to stop by and see us in Booth 826 to see these new products.

Our new GXP2140 and GXP2160 Enterprise IP Phones show off the new generation of Grandstream GXP IP Phones – an enhanced software and hardware platform featuring a rich, color screen and full-color operating system, Gigabit ports, built-in Bluetooth for applications such as syncing contacts/calendar from mobile phones, using Bluetooth headsets and for transferring calls between mobile phones and the GXP2140/2160, and a new industrial design featuring ergonomical handset and keys.

We also recently released four new infrared weatherproof IP cameras which are ideal for outdoor use in settings where weather and light are a concern. The GXV3672_HD_36 and GXV3672_FHD_36 (3.6mm lens), GXV3674_FHD (vari-focal lens) and GXV3610_FHD (3.6mm lens) wlil all be on display at our booth, along with our full line of IP Video surveillance solutions.

We will also be displaying our UCM6100 series IP PBX Appliance and will demonstrate how it is the ideal cornerstone for a voice, video, data, and mobility solution for SMBs.

We will also be running two UCM6100 series Training Workshops at IT Expo:

  • One in Spanish, January 29, 1-4pm, sign up here
  • And one in English, January 30, 1-4pm, sign up here

VS:  What’s your booth number and the #1 reason someone should stop by and say hello?

Grandstream:  Grandstream will be in booth 826. Look for the tall white tower with Grandstream branding on top of it.

The #1 reason why anyone should visit us at IT Expo is that we will be demonstrating an entire working solution and will have all of our products ready to play with.

To add to that point, we will also have a few really (really!) exciting upcoming, unreleased products on display. 2014 will certainly be Grandstream’s largest IT Expo booth and largest IT Expo presence to date so visitors will not want to miss out.


Questions about VoIP devices and services are regularly submitted to VoIPSupply.com through a technical support ticket or via the “Ask The Expert” tab on our product pages.

We respond to these requests directly but more often than not, this Q & A would be helpful for lots of other folks.

Below are your VoIP questions answered – Real questions from real people  just like you.

Grandstream GXP1400

Q: Will the Grandstream GXP1400 work with a Google Voice account?

A:  The short, simple answer is, “Yes.”

Google Voice itself is not a phone service, it’s more of a liaison helping to get all of your different phone numbers (work, home, mobile) working together under one Google Voice number/account.

In the words of the About Google Voice  page:

Google Voice works with mobile phones, desk phones, work phones, and VoIP lines. There’s nothing to download, upload, or install, and you don’t have to make or take calls using a computer.

If you don’t already have a SIP provider, the Obihai OBi100 and Obihai OBi110 are analog telephone adapters designed specifically to make calls through SIP or Google Voice. In fact, they’re the only ATA’s that work natively with Google Voice.

This might still leave some unanswered questions about VoIP and Google Voice so check out this article, Google Voice: a cheapskate’s guide to cheap VOIP.

Aastra 6757i with 675i Sidecars

Q:  Do you have a recommendation for a headset that will work with an Aastra 6757i with a 675i sidecar?

A:  The Aastra 6757i VoIP Phone connects to headsets through the RJ22 jack on the back of the phone. It also is Electronic Hookswitch (EHS) compatible, with the right adapters, for wireless headsets.

Here are some options:

Jabra PRO 9450

This wireless headset is compatible with the 6757i by using a DHSG cable (Model # 14201-10). The Jabra PRO 9450 offers three wearing styles, wireless range up to 450 feet, and 4-way call handling.

Plantronics Savi W730

The single ear Savi W730 is a DECT headset with an over the ear wearing style, a noise-canceling microphone that reduces background noise interruptions, and 3-way connectivity to easily manage and switch between PC, desk phone, and now mobile calls from a single wireless headset.

Plantronics recommends using the Aastra DHSG Cable Kit for Remote Hookswitch.

A warning from the Plantronics website:

DO NOT connect the APS-1/ APS-10 directly to this phone, but via the DHSG adapter cable. Any damage caused by connecting the APS-1/APS-10 to the phone will void the phone warranty.

Or you can make a connection from the Savi W730 to the Aastra 6757i by using the Plantronics HL10 Handset Lifter.

Sennheiser CC 520

The Sennheiser CC 520 is also compatible with the Aastra 6757i and is a binaural corded headset with an ultra-noise canceling microphone. The CC 520 has been designed for all day use with comfort pads in the headband and specially padded ear caps. Use the Sennheiser CSTD01 QD Cord to easily disconnect the headset from the cable.


Lightweight and stylish, the VXi Tria V DC convertible headset also offers three different wearing styles—headband, earhook
and neckband—so you can choose the one that best suits your need and preference.

Grandstream GXV3140
Grandstream GXV3140 Skype Video Phone

Q:  Can I use this phone [Grandstream GXV3140] with a USA number while I am in Mexico for 3 months? If someone calls my Skype number will it ring in Mexico? I will have a cable router and be in a fixed place. Thanks.

A:  The answer is “yes” to both parts of the question.

The beauty of VoIP is that as long as you have an internet connection and your GXV3140 is provisioned to remotely access your VoIP network, you will be able to use your existing, local number anywhere in the world.

In regards to the second part of the question, the GXV3140 is a Skype certified IP video phone so again, as long as your phone is connected to the internet and someone calls your Skype number it will ring wherever you are.

In the words of the Grandstream GXV3140 user manual:

The GXV3140 allows free voice and video calls via Skype simply by plugging it into the network, or through your IP PBX with a user friendly web GUI.

When you receive an incoming Skype call on the GXV3140 you’ll see the Skype call window pop up on the phone. From there you can select “Accept,” “Accept Audio,” or “Reject” before you start talking.  This phone also supports Call Hold and Resume when using Skype so that you can take any other calls that come in.

Keep the Skype application open or simply minimize the window so that you only have to sign in to Skype once and you’ll be able to receive Skype calls as they happen.
