I am trying to troubleshoot an issue with internal calls.
Two endpoints are registered to GnuGK 2.3.1 (CVS).
If firewall traversal is enabled on the Polycom HDX endpoints, then
internal calls dialed via the H.323 ID fail. The two endpoints will
play the "ring ring" sound and will display the distant ends' system
name, but they will fail to establish a media channel and will then
disconnect.
If firewall traversal is disabled, the calls can connect.
I'm not even sure I need firewall traversal, as the endpoints can reach
the GK without passing through a firewall, but it seems odd that the
GnuGK isn't recognizing that the two endpoints are internal.
In the level 5 log, I can see:
