Along with the debug h323 h225 event, debug h323 h245 event, and show local-host commands, this command is used for troubleshooting H.323 inspection engine issues. You need to have a rule to translate the address back from the outside address to the inside - note that on the ASA, software version 8.3 and above allow you http://haiteq.com/cisco-asa/cisco-asa-rdp-not-working.php The translated Interface is the outside interface.

The following is sample output from the show h323 ras command: hostname# show h323 ras Total: 1 GK Caller This output shows that there is one active registration

For the local endpoint and foreign host, there are 0 concurrent calls. Unsolicited RTP/RTCP UDP packets to an inside interface does not traverse the ASA, unless the ASA configuration specifically allows it.

That is, is the issue with: the ASA SIP inspection is not working as expected your local SIP clients trying to self-NAT or STUN RTP is the remote SBC just crazy? Otherwise, you are specifying the class you created earlier in this procedure. All the extensions are successfully registered on PBXnSIP domain panel, and when dialing you can hear the destination extension ringing, but when somebody picks up the phone, no sound, however the If you intend to use one of those techniques, first create the regular expression or regular expression class map.

And I have trouble to get audio working when my IP PBX is configured to receive inbound calls on another port than 5060. For example, if the match not command specifies the string “example.com,” then any traffic that includes “example.com” does not match the class map.
