ASA SIP inspection

Hi All,

we are having an issue with ASA sip inspection. here is our topology:

CUCM-A --> ASA-A -- > ASA-B --> CUCM-B

phone from site A calls site B, call is connected and media is being passed. when phone in site A puts the call on hold, the call is dropped immediatly. I did packet capture from ASA-A egress interface, and it is sending its own public IP address in SDP contact when phone A puts the call on hold. is it supposed to be 0.0.0.0 when phone A puts the call on hold?

appreciate any suggestion

Alex

Hello,

As long as I know that behavior of setting the SDP contact as 0 has been deprecated,

Check the following RFC for more comments

Thanks for the link, but even I don't see "audio=inactive" in SDP header coming from ASA-A.
