If SIP endpoints are firewall and have public ips (3g networks, governmental organizations, ...)
we run into issues. Sure there are some workarounds to force it to a traversal call but thats not realy good.
What I lack is the capability to set based on source ip or source alias a forced NAT (or also forced no-NAT (not
only for sip also for h323 h460.18)) handling on the VCS.
Also the STUN server seems to lack the test with the secondary ip address to detect "symmetric" firewalls/nat.
Also the endpoints could have settings to disable h460.18 as well as for sip a setting to force traversal calls (on endpoints, but also on Jabber Video)
Also ICE support on TC/TE endpoint is missing.
Are there any plans to have an improved firewall handling for sip on the VCS and endpoints?
What are suggestions / workarounds regards that?
