The SIPxchange alias function and XML data format used for SIP.edu is described in the Administering Pingtel SIPchange manual in the SMTP to SIP URL translation section.
SIPxchange is also providing SIP service to about 50 hard and soft phones. These phones are reachable via SIP.edu and can also place and receive PSTN calls via the gateway to the PBX. SIPxchange is also providing voice mail service to the SIP phones. SIP devices are assigned a ten digit North American dial plan number to allow for caller-id compatability when calling out to the PSTN.
MIT is using a Cisco 2611 gateway with one PRI to our Lucent 5ESS PBX. The gateway is currently running IOS Version 12.2(11)T .
