[Asterisk-Users] Fw: Interconnecting to an Altigen PBX?

[Ian McLaughlin]

Has anyone got Asterisk talking successfully to an Altigen PBX using h323?
I can successfully make calls from Asterisk to Altigen, but calls from
Altigen to Asterisk get a fast busy.

There seems to be a lack of h323 example files (or maybe I'm looking in the
wrong places) as well as a severe lack of h323 documentation from Altigen.
Any pointers would be greatly appreciated.
