Hi SIP Implementors, I am seeking your guidance on an interop issue with a third party PBX. They are sending an invite with a Contact Header that looks like this:
Contact: <sip:anonymous.invalid;[email protected]:5060;maddr=10.10.10.10;transport=udp;user=phone> Please note I have changed the domain and the IP. We reject the INVITE with SIP/2.0 400 Bad Request - 'Malformed/Missing Contact field' In RFC3261 I see that the INVITE must contain a Valid Contact Header to be used for subsequent requests, but I'm not sure if the above is valid. Can anyone comment? Thanks, -- Adam _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
