[SIPForum-discussion] Port numbers problem

[Mudugere, Satish]

While socket binding local port (sending RTP packets from local to remote) can be anything, but the remote port must be the one received in media line of SDP. In your example it is 18990.

Subject: [SIPForum-discussion] Port numbers problem

Hi,
I need some clarification regarding binding port numbers when sending RTP packets.

I am using network sockets in developing my SIP Client. When I send my RTP packets to the SIP Server which port should I locally bind to i.e my client should be binded to which port number, should it be the SIP Port = 5060, or the port number which I have sent with my INVITE which is m=audio 18990 RTP/AVP.

Can somebody give more information regarding this.

Regards
