Using the GNU Gatekeeper with Cisco / Tandberg Endpoints, Gatekeepers or VCS

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:


URL Dialing (Annex O Dialing)

Older versions of the GNU Gatekeeper didn't fully comply with H.323 Annex O when dialing destinations of the form This is fixed in GnuGk 2.3.2. Make sure you enable the 'srv' routing policy in GnuGk's configuration.
