If You Like your Phone System You Can Keep It

SIP trunking for legacy PBX and Key systemsBusinesses 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.

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.
