- SCTP support introduced in the trunk

Courtesy of Glenn Marmon, Connecticut College Class of 2007, who submitted the patch, OpenSER includes now support for SCTP (Stream Control Transmission Protocol). It completes the list of the possible IP transport layers that could be used with SIP in OpenSER.

You can find details about SCTP at: http://www.sctp.org/

Basically, it is a reliable transport protocol, like TCP, but provides a number of functions that are critical for telephony signaling transport (read more about the benefits: http://www.ietf.org/rfc/rfc3286.txt).

If you have the chance to own a SCTP-aware SIP phone and can test, please provide us feedback on the mailing lists. Hope SCTP will gain more and more space, as it seems to be the right protocol for VoIP/IM&P signaling.
