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.

Why Choose Us

How do you beat competition if your communication system is not ready to meet the increasing number of customers?

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.


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.

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.

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?

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)

Frequently Asked Questions

Can SIP Trunking help business grow ?

If you put constant effort into your business, it grows naturally. The problem arises when you can’t keep up with the growing number of customers and employees. Each one needs your special attention and desires a quick reply. Also, remote teams want constant connection with your business to stay updated with the ins and outs. 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.
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.
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.
Our system works easily with Asterisk, Microsoft Skype for Business, NEC, Elastix, FreePBX, 3CX, Allworx, SwitchVox, Ips Mars, TrixBox , Cisco and others.
Cebod Telecom provides high call quality by supporting G.711, G.729, u-Law, a-Law Codecs for your SIP Trunking.
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.
