Using the GNU Gatekeeper with Cisco / Tandberg Endpoints, Gatekeepers or VCS
Cisco's H.323 products have a very standard compliant H.323 stack and usually work very well with the GNU Gatekeeper.
That makes it easy to add a GnuGk next to a VCS eg. when you need more firewall traversal capacity or it reaches end-of-life and needs to be replaced.
Alias Matching
Cisco / Tandberg gatekeepers or VCS ignore the case and exact type of endpoint aliases when
they are looking for a call destination. They would regard alias "Jan" to be the same
as alias "jan". To get the same behavior from GnuGk, you can set these options:
[Gatekeeper::Main]
CompareAliasType=0
CompareAliasCase=0
|
URL Dialing (Annex O Dialing)
Make sure you enable the 'srv' routing policy in GnuGk's configuration.
