Platform: ASA 8.3(2)
Hello,
I have SIP devices along with SipTrunk and media endpoints. I am having issues with the ASA not dynamically opening (sip inspect enabled) UDP ports for RTP after a SIP re-invite causes the media endpoints to change within SDP.
The problem as below.
Initial SIP invite setups properly with ports dynamically opened between the media endpoints in the ASA
Re-inivite from the SIP device causes the media endpoints to change within the SDP
ASA blocks ports associated to the new media endpoints
I can resolve this by allowing the ports in the ACL, but suprised this is not working as re-invites to change media endpoints is to be expected in SIP conversation.
Regards,
AJ
