[SIP Beyond VoIP] sip simple client msrp port config

[Adrian Georgescu]

Hello Noemi,

The ports used for media sessions whether the media is RTP audio/video or MSRP chat/file transfer are negotiated in real time using the SIP protocol, in the SDP payload, is not something you set somewhere in the client, these ports can be different for every established session.

When your client start the SIP session, the remote party will tell you the ports where you must send media in the 200 OK SIP message. When you receive a session request, the ports where you must send the media are in the INVITE you receive.

In you case is the server that must offer the ports and the client will simply use them.
