The Differences Between Primary Rate Interface (PRI) and Session Initiation Protocol (SIP) Explained

December 3, 2015 by Nathan Miloszewski

The advantages of Primary Rate Interface (PRI) service and Session Initiation Protocol (SIP) can be debated.

Both protocols use digital signals but the latter provides an advantage that allows you to customize the phone system according to your business needs.

However, it helps to educate yourself on both options before making a decision on which one is best for you.

Primary Rate Interface

What Is PRI?

PRI (Primary Rate Interface) is a interface standard associated with transmission of voice data over a dedicated line.

PRI uses a circuit switched model for voice call among people located in different locations.

How Does It Work?

PRI provides 23 voice channels that a business can use simultaneously at any given time.

Multiple users can access these 23 channels within a specified network and the hardware requirement includes a PBX (Private Branch Exchange) or IP PBXs.

However, if a business has 50 operational DID (Direct Inward Dialing) numbers, then only 23 will be available any point of time. To make all the numbers available more PRI circuits are required (which will increase your overhead).

Support Framework for PRI

Integrated Services Digital Network (ISDN) assigns the PRI service.

ISDN enables the digital transmission of voice and data service over Public Switched Telephone Network (PSTN). The PSTN is where all the global telecommunication devices are connected.

You can call to any part of the world, regardless of the receiver’s device, through the PSTN. Initially, the PSTN provided analog transmission but eventually it was digitized after the advent of ISDN to provide a faster, better quality, and lower cost service.

Session Initiation Protocol

What is SIP?

Session Initiation Protocol or SIP Trunking is a system where transmission of voice data is performed over an existing network data line by creating a virtual network between the PBX and the SIP network of the carrier.

In other words, it goes over an IP Network. It uses a Packet switched model for voice calling.

How Does It Work?

The system uses an IP PBX system rather than the normal PBX (unless it’s compatible with SIP framework). The primary reason for this is the use of VoIP rather than PSTN. The public internet and LAN is connected with an IP PBX.

The voice call in a SIP framework uses the same path allotted for non-voice transmission.

Similarly, when receiving voice data, the equipment at the service provider’s end transmits it to the designated IP PBX. Re-routing of data packets to another pre-determined number takes place when the primary number is not responding.

Support Framework for SIP

SIP uses your existing data transmission set-up. Unlike PRI, SIP does not come in a pre-determined connection bundle.

Depending on your requirements, a business can buy call paths or increase bandwidth of the existing data line.

With SIP, businesses are not dependent upon on a bundle service such as PRI. If the number of calls is less than the actual capacity, the unused bandwidth is distributed across the network for other use. This ensures a more efficient network with no wasted resources.

How To Choose Conference Phones for Remote Learning

November 20, 2015 by Nathan Miloszewski

Note: This is a guest post by Victoria Zona, Senior Channel Sales Manager, Revolabs

Distance learning has become increasingly pervasive in both corporate America and at educational institutions.

Academic institutions are all adding programs to accommodate remote students and are now offering on-line degrees.

To save money, many corporations are remotely training branch office employees on the policies and procedures bringing distance learning to corporate workplaces.

Clear Audio Maintains Focus, Increases Comprehension, Reduces Fatigue

Many times the voice quality in remote learning environments is unintelligible. Poor sound quality makes it difficult for the student to understand the material presented, and reduces their active participation.

Our industry has made great strides to improve video quality during distance learning sessions, but crystal-clear audio is even more important to keep students’ focus, increase comprehension, and prevent classroom fatigue.

Typically, there’s no technical person on hand to monitor and support the remote learning session. Therefore, having an audio solution that is simple to use and easy to setup is key.

Poor sound quality makes it difficult for the student to understand the material presented, and reduces their active participation.

How to Choose Audio Devices for Distance Learning

Here are some tips to consider when choosing an audio product for distant learning:

Seek out an audio solution that provides superior audio pickup and speaker quality so users on both the near and far end of the room can hear every word.

360° Coverage

Deploy a device that has full 360° coverage of audio capture, incorporates integrated acoustic echo cancellation, and supports full duplex audio to enhance comprehension and conversational flow.

Strong Speaker, External Connections

The speaker output on the device needs to be loud enough for the participants in the room to hear, or allows connections to external speakers to amplify the sound level in the room.

BYOD Compatible

If bring your own device (BYOD) program is supported, make sure the audio conferencing device is software-agnostic and connects via standard PC, tablet or mobile communications channels.

Cloud Compatibility

For cloud based conferencing solutions, verify that the audio conferencing device supports multiple communication applications.

Ask a VoIP Supply Representative about Revolabs audio conferencing solutions for distance learning.

We have a range of products to fit every environment, offering unmatched audio quality that allows users to hear every word.

Why You Should Trust Your VoIP Connectivity to Patton SmartNode Gateways, Routers, and Session Border Controllers

November 7, 2015 by Nathan Miloszewski

Patton Electronics provides network access and connectivity products such as gateways, routers, and session border controllers that support just about every telephony interface so that you can take advantage of VoIP in a variety of ways that suit your needs or existing infrastructure.

Back in 2012 we posted an interview with Tyler Delin, Product Manager at Patton, who gave us a background on the company.

“Patton is a family-owned-and-operated business that was started in 1984 by the three Patton brothers while students in college,” said Delin.

Delin went on to explain further:

“Patton’s niche was making modems and connectivity products for the telecommunications industry. Over the years Patton has taken those simple beginnings and expanded into a manufacturing company that today employs more than 170 people and provides over 1,000 products, with a focus on VoIP and Ethernet extension technologies. Today, Patton equipment is up-and-running in carrier, enterprise and industrial networks all over the world. We are headquartered right outside of Washington DC in the famous “technology corridor” and we have regional offices in strategic locations across the globe, with training and technical-support centers in Switzerland, Hungary, Italy, Lebanon, India and Vietnam.”

Patton SmartNode Gateways

Patton SmartNode gateways and routers integrates IP and TDM communications so that you can use voice-over-IP.

Common applications include:

Connecting traditional phones and PBX to a VoIP service provider (SIP Trunking)
Migrating a legacy PBX to an IP PBX
Gateway to the PSTN for an IP PBX

SIP Trunks Can Still Use PSTN Connectivity for Local Calls and Fallback

Patton helps you connect to VoIP but their line of SmartNode devices offer helpful PSTN features such as PSTN connectivity for local calls.

SIP trunks are great for saving money, powerful features, and more. But if your business has a high volume of local calls, continuing to utilize the PSTN with your SmartNode gateway may provide some benefits.

And if your business has multiple locations in different areas of the country, you can link Patton FXO gateways at each location via the Internet allowing you to take advantage of low cost, local PSTN calling in each region.

Additionally, for any business that relies on SIP trunking for telephony, SmartNode VoIP gateways can provide PSTN fallback in the event of an Internet outage.

Call centers live and die with voice connectivity. They can add a Patton SN4300 VoIP Gateway to their server closet to access the PSTN for failover, local calls, or just a gradual migration to VoIP and not have to worry about downtime.

Why trust Patton?

Unlike their competitors, Patton’s gateways include FREE post sales technical support and configuration help, including a 1 year warranty.
Patton’s SmartNode products offer gateway and router solutions with just about every telephony interface: PRI, BRI, T1, E1, etc so they will work with your network!
SmartNode supports SIP, H.323, and MGCP VoIP technologies.
SmartNode is a mature product, it has stood the test of time and is tested and deployed in hundreds of real-world networks.
When using 3CX, Patton works seamlessly as your gateway to the PSTN. Simply choose your Patton Gateway from the 3CX drop down menu.

Free Support and Upgrades

Patton offers the best customer support in the industry and it’s free.

You can call Patton before or after you purchase a SmartNode device and they will answer your questions free of charge.

They also offer guaranteed response and remedy times plus as 24/7 support, for an additional fee.

And if you’re in need of professional services, Patton can help you with system design, installation, configuration and more.

All Patton products have a standard 1 year warranty. Patton Enhanced Warranties are also available if your business needs advanced replacement protection should the device fail – If your unit goes down, your replacement will be shipped next-day priority at no cost to you.

VoIP Q&A: Block Caller ID on a SIP Trunk, DTMF Pause for VoIP System, Polycom Handset Warranty

October 30, 2015 by Nathan Miloszewski

Our tech support team here at VoIP Supply offers great pre- and post-sale support plus provisioning, consultations, configuration, and installation help.

We get a lot of VoIP hardware and software questions and realized that these solutions should be shared with everyone.

Here now are our top three (real) questions and answers from this past week (from VoIP users just like you).

Block Caller ID on a SIP Trunk

Q: I have a customer with a Xorcom XR1000 IP PBX. Because they are a social service agency helping battered women they would like to block incoming and outgoing caller ID on a SIP trunk.

What would be the easiest way to do that?

Is there a way to send an anonymous or unavailable in the outbound caller ID only?

A: That will be a function of their phone service provider, and I would recommend they contact them and make sure that’s a supported option.

You can try changing your outbound caller ID but you need to know if your SIP provider is overwriting that when the call hits their system.

They will probably need to add substitution rule on their side.

With some providers, you can remove the outbound caller ID field in your trunk to achieve an “unknown” caller ID, but as I previously mentioned, it’s very much a function of your SIP provider.

How to put a DTMF pause on a VoIP SIP system

Q: I’m trying to put in a pause or delay when using a DSS key for either the 3CXPhone CTI mode or Fanvil VoIP phone.

What I’m trying to accomplish is that so when I call a number and get their auto-attendant (AA), I can bypass it and dial an extension.

Is there a way of programming a custom dial to send it in pieces via 3CX through an extension or, something like that?

A: Pauses generally aren’t seen in SIP systems because all digits are sent at once.

It’s probably possible with some custom programming of a softphone, but it’s not a standard supported feature.

3CX might have a better suggestion or a custom solution. Doing a DTMF pause is a pretty asked for a feature that doesn’t really exist anymore in VoIP.

3CX has a paid support option so, if you’ve purchased that, absolutely take advantage of it. But, they also have a ticketing system (email support) which is free via http://support.3cx.com/.

What's the warranty on a Polycom handset?

Q: The Polycom IP 650 handset mouthpiece on one of the units failed. The other end can barely hear the person talking into the handset.

The earpiece seems to work fine. I swapped handsets with another unit, and the good handset works fine on the same phone, and the bad handset does not work on the other phone.

I am trying to get information if that is covered by the manufacturer’s warranty.

A: We honor a 1-year warranty with new phone purchases. We’ve located a replacement handset and are sending you another one.

When you get the new handset, don’t worry about sending back the defective handset, just be kind enough to recycle it.

That’s all for this week, stay tuned for next week’s VoIP Q & A.

How to Prevent Audio Fatigue

October 19, 2015 by Nathan Miloszewski

revolabs audio fatigue

Note:This is a guest post by Ashley Nguyen, Channel Marketing Specialist, Revolabs

Recently Tim Root, Chief Technology Officer of Revolabs, wrote an article that appeared in the October issue of Sound & Video Contractor titled “Audio Fatigue is Real.”

His report on why the brain works harder to make out sounds during poor audio communications, such as through a speakerphone with low frequencies, is spot on.

I’ve experienced audio fatigue, and I’m sure many of you have as well when you can’t understand the person at the other end of the line due to more than one person talking at once or background noise from a terrible audio device.

Look for products that have ultra-wideband technology for the most intelligible speech, automatic gain control, and noise suppression to help reduce background noise, and full-duplex telephony with echo cancellation.

From Speakerphones to Softphones – How to Choose?

Communication devices come in all different shapes and sizes: speakerphones, conference phones, mobile phones, smartphones, softphones, POTS, VoIP phones, etc.

There are so many to choose from, but which help to prevent audio fatigue?

Tim cited in his article, the brain can easily recognize high frequency signals ̶ such as when I’m yelling ̶versus low frequency ̶ as when I’m mumbling.

“Look for products that have ultra-wideband technology for the most intelligible speech, automatic gain control, and noise suppression to help reduce background noise, and full-duplex telephony with echo cancellation,” he wrote.

Revolabs FLX UC 1500 IP & USB Conference Phone (with Extension Microphones)

Revolabs FLX UC 1500 IP & USB Conference Phone with Extension Mics

Revolabs Helps Overcome Audio Fatigue

Make sure you have great audio products.

Revolabs offers unsurpassed solutions to help overcome audio fatigue. The FLX™ UC line has full-duplex technology and acoustic echo cancellation, as well as other attributes that Tim mentioned above.

In particular, the FLX™ UC 1000 and 1500 offer ultra-wide bandwidth, up to 16kHz, which is favorable for intelligible speech.

Don’t suffer from audio fatigue again!
