SIP Trunking

SIP trunking transforms your business into a high-tech brand, enabling it to meet the need of growing consumers.

What is SIP Trunking

SIP Trunking allows business to virtually connect to the Public Switched Telephone Network and routes all VOIP calls and unified voice data over internet. One of the most significant advantages of SIP Trunking is its ability to combine data, voice, and video in a single line. Therefore, eliminating the need for separate physical media for each mode.

VOIP Phone System with SIP Trunking

Several businesses use VOIP phone service for outbound and incoming calls. Similar to VOIP, SIP Trunking also uses shared lines, internet connection for unified communications and is a more flexible and cost-effective communication protocol to develop, modify, and terminate various applications like voice calls, video calls, messaging applications, etc.

Also with SIP trunk, its less expensive to buy Direct Inward Dialing number (DID) or a local, vanity or toll free phone number.

Cost Reduction

Traditional phone calls need wiring, hardware, and circuit boxes to maintain a PSTN connection. SIP trunk, on the other hand, is virtually installed on your existing internet connection which completely eliminates the need to connect to traditional phone lines. This single quality of SIP saves you a lot from physical installation costs.

With traditional phone lines, there is a vast difference between charges of local calls and international costs. SIP trunk is based on the internet, so the charge difference is much shorter. An additional benefit of SIP trunking is that you only pay for lines you use as opposed to traditional systems where you have to pay for all phone lines, no matter whether you use them or not.


Traditional phone line systems do feel like a real headache when it comes to add, modify or delete phone lines. It requires the phone service company to go through an entire procedure of making changes to the existing system (hardware purchase, installation and maintenance cost) and charge you for the same.

The more channels you require, the more you have to pay for extra installation charges. And the more time you have to wait before the system starts working as per your requirements. With SIP trunking, just request the SIP service provider to add another channel in a matter of minutes. There are no extra charges or waiting for the installation guy.

Reliability and Security

How secure is your traditional phone system in the case of emergencies? And how would stay connected with your customers and remote team if something goes wrong with phone lines?

Being connected through wired phone line systems are as good as the conditions allow. The moment something goes wrong (maybe a fire), all your connections are lost. SIP trunk forms a virtual connection between your business and clients. Consider it invisible so physical issues won’t affect it much. Even if something happens out of the blue, SIP reroutes the data or call to the available mobile phone to keep your business going despite all odds.

Minimized Maintenance

Where there is no requirement for physical connection like wiring or circuit boxes, your maintenance time and charges are reduced to a great extent. There’s no need to look after analog or IP infrastructure as a ritual of keeping your phone system alive and increase the bills in the name of maintenance.

How does it work?

To understand SIP trunking, you first have to acknowledge how the traditional phone system works:

You simply dial the number, it passes through PBX, crosses PRI or copper lines and finally reaches the phone you are calling. The process is the same when a customer calls you or you call a customer. PRI lines hold the capacity of a maximum of 23 calls at a time. Not more than that.

SIP trunking, instead of copper line, carries your calls through an internet connection which gives it an infinite capacity to make multiple calls with multiple channels.

Important terms to understand:

PBX stands for Private Branch Exchange (popularly known as traditional phone system).

ISDN (Integrated Services Digital Network) connects one call to another via copper lines. In USA, its has a capacity of 23 lines (PRI) and in Europe it has a capacity of 30 lines ( E1 lines)

With its qualities such as increasing channels at any time and low maintenance costs, SIP trunking allows your business to keep up with the pace.
Relocating business to another city, Can I keep the same phone number ?
Traditional phone system costs you a fortune if you relocate your business. All those wiring, installation, area code changes, phone number changes, etc., eat away your valuable time and money. Being a virtual master, SIP trunking allows you to keep your existing numbers with your new location. No hassles at all.

How do create local presence for business ?
Want to be available in all areas of your country, but unable to expand your branches? SIP trunking covers you there too. It creates virtual local presence of your business with local numbers in cities where you don’t have physical presence. For example, if your office is located at Chicago, SIP trunking creates local numbers for NY, Boston, Los Angeles, etc., and redirect it to your Chicago office.
Are your SIP Trunks compatible with PBX platforms?
Our system works easily with Asterisk, Microsoft Skype for Business, NEC, Elastix, FreePBX, 3CX, Allworx, SwitchVox, Ips Mars, TrixBox , Cisco and others.
How many SIP Trunks should we buy ?
With a SIP trunk, you need to figure out how many inbound and outbound simultaneous calls will be made on daily basis, and then buy an appropriate number of trunks. For instance, if your company has 20 employees, and you expect about 8 simultaneous calls at any given time. In that case, you should buy 10 SIP lines, leaving some room for adjustment, if ever needed.
