SIP Trunks for
Legacy PBX and Key Systems
If You Like your Phone System You Can Keep It
Businesses often face the decision of whether or not to do a forklift upgrade of a working small business analog key system just for the purposes of going to VoIP to reduce monthly telecom costs. Because these key systems aren't IP-enabled and don't support SIP trunking, business that want to take advantage of SIP for cost reduction are often forced into a completely new systems upgrade when, in reality, the existing system serves them fine. A new system with SIP trunking does show an ROI payback due to lower monthly telecom spend in the 3-5 year range, but requires a significant initial investment.
SIP in Action
One medical office was able to reduce their monthly telecom bill from $695 to $250 by adding SIP.US services and two analog telephone adaptors to their old Nortel system.
How it Works
SIP.US offers an interim step that can allow you to keep your existing hardware yet fully realize the monthly telecom cost savings by moving to a SIP trunking solution. By deploying a small, multi-line analog telephone adapter in conjunction with the existing key system, the phone lines going out to the phone company can simply be plugged into the adapter box. The adapter converts the analog lines to SIP and the calls flow through the existing Internet connection to the SIP.US servers. Cost savings can be 40-60% per month and, better yet, there's no forklift upgrade of the existing system.

Low cost and good!
It’s easy to be low cost, but it’s a lot harder to be low cost AND good! In my opinion, SIP.US should be on anyone’s short list of primary providers.
All the tools I need.
The SIP.US Control Panel gives me all the tools I need to add, change and delete phone numbers. I can even order all the DIDs I need and set them up instantly. I love having access to these self-service tools, but I know the support team is also there if I need additional help.

Quality support, low price.
I wasn’t sure how to configure my Asterisk system to work with SIP.US. The SIP team was able to remotely access my system and set it up for me. I didn’t expect that level of support for such a low price.

I don’t have any experience with SIP trunking, but connecting my Asterisk PBX to SIP.US was fast and easy.

The reason we moved most of our VOIP to you is because of your excellent support. We moved from another provider but your support makes the extra money well worth it.
