Additional to a selected lists of SIP features implemented by the underlying PJSIP library and exposes through a Python API, this project implements session based instant messaging (IM), file transfer and multi-party chat sessions using MSRP protocol and its relay extension, publication and subscription for rich presence information such as availability, moods, activities and geo-location, management for presence rules, resource lists, RLS services documents using XCAP protocol.
== SIP transport ==
* Multiple accounts support
* UDP/TCP/TLS
* RFC 3263 DNS lookups
* SIP trace
== SDP negotiation ==
Supported media types:
* Audio (with or without ICE and STUN)
* Instant messaging over MSRP (with or without MSRP relay support)
* File transfer over MSRP (with or without MSRP relay support)
* Desktop sharing (VNC over MSRP)
Except MSRP file transfer, all other media types can be combined together.
