SIP Trunks over a Private Network

Maximize your IP phone system investment with a single connection for voice & data
For businesses that want to realize the cost savings promised by their investment in an IP phone system, SIP trunks will provide secure connectivity to the public switched telephone network (PSTN) over a shared Internet connection.

What is a SIP Trunk?
A SIP trunk is a flexible, virtual ‘trunk’ that allows you to make and receive local and long distance calls over an IP connection eliminating costly investment in dedicated voice trunks. Session Initiation Protocol (or SIP) is used to open a secure channel on an IP connection to deliver voice calls.

SIP Trunks are a great solution for businesses who want:

  • To maximize their investment in an IP-enabled PBX or key system
  • To consolidate voice and data traffic on a single network connection
  • The flexibility to quickly add or remove capacity to match fluctuations in business call volume.

Should you use SIP Trunks or Traditional Analogue Services or PRI Services?
Quick answer is yes… why not both? I think there is an error in the process of using one technology to eliminate another (I cannot believe that I just said that). Let me try again, I think the idea of ‘reducing’ your dependence on the legacy copper lines is a good idea. I would not eliminate all of them. Start with the idea of 50 percent. Or for those conservatives in the crowd, don’t reduce, just stop ordering new legacy links. From there, consider using SIP Trunks for your outbound calling and reserve your legacy trunks for incoming lines. I think it will be almost immediate that you will realize the overall improvement in toll qualify when comparing a Frontier SIP Trunk to a traditional PRI or moreso, a traditional analogue line.

When you are comfortable, let us ‘PORT’ your phone number to our SIP ring group. And when ready, further reduce your legacy trunks even more.
