Voice Over IP (VOIP) at CSAIL

TIG has been working with IS&T since the spring semester during their pilot programs for moving the campus over from ISDN phone service to voice over IP technology. Currently most new lines deployed and existing lines moved in the lab have been converted to VOIP, primarily utilizing their OpenSer? SIP server. At present we have roughly 64 voip lines. Most are attached to desk phone sets but a few are deployed through computers using software on multiple platforms (commonly known as softphones).

Recently, we have been assisting in the testing of IS&T second server, Sylantro. This server has the primary advantage of providing a basic function we had with our ISDN service, that of shared line appearances.

We have deployed several models of VOIP phones but we (and IS&T) have settled on the Polycom 550 IP and the Polycom 650 IP. Here are the manuals for the models currently deployed in CSAIL:

In addition, here are the pdfs for the quick help guides to the new Sylantro system:

If you have any questions or wish to try out VOIP, please email us at ops@csail.mit.edu
