VOIP Pilot at CSAIL

The Infrastructure Group has been involved for over a year in a pilot rollout of a voice over IP (VOIP) initiative that is headed by MIT IS&T. MIT will likely transition away from its current telephone service model, which is based on the 5ESS telephone switch in building E17, towards a mostly IP-based model by 2009.

As part of the pilot, tig has completely transitioned all of its own phones and emergency lines to VOIP to test performance and to discover potential bugs in the system. As of this writing, there are two distinct VOIP services being run by IS&T.

The "devel" server

This VOIP server is based on the Asterisk PBX software package and has been largely opened up to tig for administrative capabilities. The service can run over the CSAIL network, MITNet, or even from your home ISP. This service is not considered enterprise class and comes with no guarantee of service. It is suitable for research purposes and offers more flexibility than the enterprise solution (described below)

The "enterprise" server

This VOIP service is based on the commercial Sylantro package, and is intended for enterprise-class service. Provisioning of phones is done using DHCP on MITNet, so it will not run (at the time of writing) over the CSAIL network. We are working with IS&T to improve this condition.
