I am having issue with traversal zone in VCS and VCS-E. there is a traversal client zone in VCS-C with H.323 and SIP enable. when dial out to the internet endpoint, which is H.323 endpoint, VCS-C uses SIP instead of H.323 and I am getting this error message "Invalid alias for SIP interworking". I want VCS to make H.323 dial to the VCS-E instead of SIP. On the other hand, I don't want to disable SIP in traversal zone.
If you show me how to resolve this issue, I'd very appreciate.
if you check the zone status for this traversal client zone on the VCS-C, does this zone display as 'Active' both for H323 and SIP?
From what you describe, it sounds like the H323 portion of the traversal zone is not properly up, which is why the call would go out on SIP. If this is the case, I would recommend you check that the traversal zone is configured identically on the VCS-C and VCS-E (With regards to port and protocol for H323), and that your firewall has been configured to allow this outbound traffic.
