Upgrade Alert: What is Elastic Sip Trunking?

According to Stock News Magazine, The SIP Trunking Services Market will reach $28.8 billion by 2025. That’s an 18.5% increase from 2018. 

Elastic Session Initiation Protocol (SIP) Trunking is an advanced and very resilient type of SIP Trunking. It incorporates cloud computing to provide flexible, reliable, and granular IP communications.

Such communications are as cost-effective as they are sophisticated. Users receive the same benefits from elastic SIP Trunking no matter how they connect to the public switched telephone network (PSTN).

Whether they connect through a premise-based PBX or cloud-based PBX, the quality is the same.

Now, you can upgrade to a more robust version of SIP Trunking called elastic SIP Uniform Resource Identifiers (URIs). Before we continue with the benefits of SIP Trunking with elastic SIP URIs, let’s take a step back.

Let’s discuss what SIP Trunking and elastic SIP Trunking are.

What Is SIP Trunking?

Session Initiation Protocol (SIP) Trunking delivers unified communications and telephone services over the internet. SIP is a function of Voice over Internet Protocol (VoIP) technology.

It works with a SIP-enabled, private branch exchange (PBX). It allows video and voice communication over the internet without involving the telephone company.

It allows virtual connections that link your business phone system to the telephone network using your already-established internet service.

Virtual Phone Lines

You enhance your communications network with SIP. SIP trunks are virtual phone lines with which you can send and receive phone calls to anyone around the globe. It doesn’t matter if they are using VoIP or a regular landline.

SIP trunks break your voice calls down into digital packets and rout them across the network to reach their intended destination.

Cost-Effectiveness of Sip Trunking

Cost cutting comes by way of pooling your resources. You use the services you already have like bursting, call recording, and Enhanced 911 (or E911) emergency calls. You don’t have to replace your phone system.

With SIP Trunking, you can expand the capacity of your system as you need it. With regular PBX plant, you buy service bundles, though you may not use most of those services except during peak times.

What Is Elastic SIP Trunking?

Elastic SIP is a virtual connection, meaning you can scale up and down as you need to during peak times. For example, many businesses have seasonal spikes in their call volumes.

With elastic SIP Trunking, you can also merge data with voice services. You can maximize your bandwidth using your IP network for both. Further, it’s easy to move services to the cloud. Voice naturally bridges to the cloud.

Manage PBX and SIP Together

Ultimately, you can manage both cloud PBX and SIP users through the same portal. Your organization experiences uninterrupted service across data centers.

Integrating with cloud services also means you can spread your Elastic SIP service architecture across multiple regions on a global scale. This creates an infrastructure that can handle redundancy and remain resilient against latency.

Unlimited Call Capacity

Other benefits include unlimited concurrent call capacity. Your people can make as many calls as they need without incurring extra charges.

Usually, SIP Trunking demands that you select and pay for the maximum concurrent call capacity that you may need during peak times. With elastic SIP Trunking, you only pay for what you use as you use it.

Monitoring Granular Usage

Organizations can monitor usage and the costs associated with them in real time for endpoints, phone numbers, gateways, trunks, channels, calls apps, and E911.

By administering at such a granular level, you can create an on-demand, truly scaling SIP Trunking service solution

Upgrade with Elastic SIP URIs (URI)

A SIP (sometimes called a SIPS URI) identifies a communications resource. A SIP Uniform Resource Identifier (URI) is the addressing scheme that indicates who to call via SIP. It identifies the user.

The user may be an extension number or SIP user number for calls going out to a softphone or VoIP phone. Basically, SIP URIs are the users’ SIP numbers, or SIP phone numbers if the line is supported by SIP Trunking.

The SIP URI looks like an email address. The exception is that a SIP URI is used to share phone conversations instead of emails.

Like any URI, you can place SIP URIs in web pages, email messages, and printed materials. They contain enough information to initiate and hold a communication session with the resource.

SIP URI Format

Here is the format: sip:x@y:Port where x=username, y=host (the host is the IP or domain)

The domain may be a qualified domain name or IP address. The SIP Trunking ports are optional. If it’s not specified, the system substitutes with a standard value of 5060.

An example of a SIP URIs is 442035638753@sip.mydomain.com. Another example is user26@13.14.10.23:5090.

Bypass the PSTN

SIP URI calling bypasses the PSTN altogether and uses only internet protocol. To use a SIP phone to dial a SIP address, you need to program the SIP address using the user portal. Then, you can use your phone address book to “dial” the SIP address.

You can use the “click2call” command on your computer, which connects your phone to the receiving phone. Alternately, you can enter the number into your VoIP phone’s speed dial. Then, all you do is select one or two numbers to call the SIP address.

Cost Savings Benefit

Elastic SIP URI dialing means once you have a SIP URI, you can send and receive unlimited calls to and from other SIP URIs with no added cost. Again, this is like email.

Once you install the email client, you send as many messages as you want and need. Likewise, having a SIP client allows you to do the same as long as the call recipient also has a SIP URI.

Multi-platform Communications Solution

Sip Trunking with SIP URIs is the most powerful as well as cost-effective communications solution. It allows almost unlimited calls over a system that’s scalable and efficient.

At the rate the technology is expanding, the traditional standalone PSTN is fast becoming a thing of the past. Contact us today to learn more about SIP Trunking.
