SIP Trunking

SIP Trunking: What is it?

A term like SIP trunking sounds complicated, but it really isn’t. Session Initiation Protocol (SIP) is the industry standard for connecting interactive multimedia users. A trunk is a link that can support several multimedia sessions at once.

Put them together and you get SIP trunking. A SIP trunk replaces a conventional telephone trunk with the Internet. This enables your business to communicate with virtually any telecom user worldwide.

Can’t I already do that with my VoIP system?

The simple answer is yes, but it is probably costing you a premium. SIP Trunking allows companies like yours to only pay for the number of lines they need, as opposed to fixed fees and contracts for analog lines or partially-used T1s and PRIs.

You realized the savings by either purchasing only the necessary number of lines or by paying by the minute. This allows your business to make more efficient use of your communications and reduce costs and eliminate wasted resources.

So what’s the catch?

In order to take advantage of SIP trunking, a business must have a VoIP PBX which supports the SIP protocol (don’t worry, most do). You’ll also need an internet connection, and a gateway between the PBX and Internet (we’re here to help).

You’ll want to make sure you have a good firewall to maintain security. We’ll work with you to make sure firewalls stay secure and are configured correctly to support a high Quality of Service (QoS) using SIP trunking.

Internet & Telecom Carrier Services

Have you ever spent hours or even days trying to resolve an issue with your telecom or Internet provider? If yes, we’re sure you aren’t anxious to do it again. Most mid size and small businesses simply don’t have the time.

Wouldn’t it be great if you could get someone else to deal with these companies? CIT offers Carrier Services. We have long-standing relationships with all the carriers and vendors serving greater Detroit and the State of Michigan. With most providers we have a preferred partner relationship which gives us direct access to priority support.

Let CIT manage your internet and telecom carriers and vendors, while you devote your time to your business.
