We have a current setup of an SM 6.1 linked with a CM 6.0 media server using a G450 as a gateway, all of which are NATed behind a Checkpoint firewall (1-to-1 for SM and CM). We have no problems sending out calls through the far-end SIP entities, however we somehow can't get inbound calls from those same SIP entities even though we had all the routings/dial patterns already set.
When we did a traceSM on the call we saw that the domain is still set at the SM's public IP thus is not recognized by SM to be an authoritative domain. We were forced to do a regular expression on the called number but when it finally got to CM it replied with a "488 Not Acceptable Here" SIP message. We also got these denial events after that particular message:
To be honest, we're a bit stumped right now as to what's keeping the call from getting to a CM extension.
