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 The Lynksys PAP2T is End of Life – it has been replaced by the Cisco SPA112 VoIP Adapter.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.

Thanks for your questions!

Usually in our VoIP Q & A Blog Series, we answer questions about submitted to us through tech support tickets on VoIPSupply.com or via the “Ask The Expert” tab on our product pages.

This time we’re sharing the questions and answers from the Grandstream UCM6100 PBX webinar that was held as part of our Grandstream Learning Series.

These were real questions from the attendees that were answered by Grandstream’s tech support team. We hope that this is a comprehensive guide on how to use a UCM6100 series PBX and what they’re capable of.

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.

asterisk

Asterisk

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

Thanks for your questions!

Many of you may know that Linksys manufacturers a solid, well used and liked Analog Telephone Adapter (ATA) product line. The product line consists of the SPA2102, PAP2T, and SPA3102. For this blog we will focus on the SPA3102 and its “added” capabilities.

On the analog side of things, the SPA3102 can act as a fully functional one- port FXO gateway since it contains an FXO line port. The FXO port can also act as a PSTN failover capability in case the Ethernet network ever fails or drops. It also contains an FXS phone port to connect an analog telephone into. Service providers often times will utilize this device providing their VOIP service to the phone port, and still allow users to use their traditional PSTN or POTS service through the failover capabilities. This is an all around great solution for the home user who would like to leverage VOIP calling through a provider, but still needs the reliability and functionality to their existing, much more expensive, but most reliable PSTN landline network.

On the digital side of things, you will notice that the SPA3102 has two Ethernet ports, a WAN or LAN or Ethernet/Internet ports. This device has built in router capabilities, which can interface both with your public internet service provider as well as your LAN. The device also has the capabilities to act as a DHCP server and “hand out” LAN addresses to your internal LAN equipment. The only downside is you will most likely need a LAN switch to extend, and service network equipment since the SPA3102 only has one LAN port.

Linksys ATA                                               

So what are the added benefits of this $64.99 device you may ask? Home users have been known to take advantage of the FXO port in a most cost-saving effective manner. Let’s describe a quick scenario first and where the gateway aspect of the SPA3102 comes into play. A home user has two locations a great distance apart, let’s say NYC and Alaska (since I’ve always desired to travel there). I am constantly making calls from my Alaskan location to the location in NYC, and to all my buds in the NYC area (local Telco calls) Traditionally, I would pick up my PSTN phone in Alaska and call my friends or location in NYC and incur heavy long distance charges from my telephone provider. In come VOIP and the SPA3102. I simply purchased (2) SPA3102′s and placed them at each location. I then plugged an analog telephone in each of the unit’s phone ports and assigned a VOIP extension, (100 for Alaska and 200 for NYC). Now I can simply pick a phone at any location and call the other for FREE all through VOIP, using NO VOIP provider whatsoever. Next I plugged my telephone line into each of the unit’s FXO ports at both locations. Keep in mind I am still paying for my traditional telephone service at each location. Now, when I pick up my phone in Alaska, I can call into the SPA3102, gain access to my local telephone service in NYC and call as many contacts as I wish in NYC for FREE.

The reason is that when my call comes into the NYC SPA3102, it traverses the VOIP network from Alaska to NYC, (where my Telco whacks me with long distance fees), and when I gain access to the local Telco in NYC, my call from Alaska “looks” local to the NYC Telco provider and I incur no long distance fees whatsoever. This whole process of “extending local dial-tone” has been a blessing in disguise to home users who frequently pay high long distance fees from their telephone. If it makes you feel better, you’re tricking your phone company, and even better, this scenario will work at virtually any location where you have broadband internet access, so you can pick up and move virtually anywhere in the world.

If you like paying long distance fees from telephone providers then continue on with the ever-increasing fees that never seem to stop, or call VoIP Supply at 1-800-398-8647 and speak with me or a dedicated sales representative about this solution, and start saving money!!!
