[SIPForum-discussion] SIP Glare

[Aniella Juverdeanu]

Hi,

But for SIP signaling one port is used (in majority of the cases port 5060) for multiple calls at each SIP end point.
If you refer to RTP then you use different ports for - each RTP endpoint will have a port from which will send the RTP packets and will receive the RTP packets for the duration of one call. The ports are sent in SDP m= line - so it doesn't matter that the far end happened to send the same port  as the originator - the ports are at different IP addresses.

Hi,

If you are using same port for both incall and out call then Glare
condition will be created.
