I seem to be having an issue with inbound calls from my SIP ITSP (voip.ms). Calls are reaching my voice gateway (CME Version 8.6) are failing with an error SIP/2.0 400 Bad Request - 'Invalid Host'.
I am getting the SIP Invite message but respond with SIP/2.0 400 Bad Request - 'Invalid Host'. From what I can see from researching this issue it is likely caused by a natting issue.
I am also seeing the following right before the 400 error:
000265: Oct 13 23:05:19.948: //-1/xxxxxxxxxxxx/SIP/Error/sipSPI_validate_own_ip_addr: ReqLine IP addr does not match with host IP addr
000266: Oct 13 23:05:19.948: //-1/B5A63090801E/SIP/Error/sact_idle_new_message_invite: Invalid URL in incoming INVITE
I have tried both with and without SIP ALG enabled on my firewall. Both seem to fail.
Anyone have any ideas?
