[Asterisk-Users] h323

Thu Aug 4 10:11:19 MST 2005

I am using asterisk-oh323-0.7.2-pre and CVS Head of Asterisk.

Oh323 Module compiled without errors. But When I try to stary Asterisk
with the Oh323.so file in the modules folder, Asterisk is dying with the
following error.

I would appreciate if somebody can give a clue to fix this error.

Thanks Juan for the information.

Altus, about the gatekeeper... It acts like a "DNS" on the h.323 world. 

Defining the gatekeeper:
1. Component of an H.323 conferencing system that performs call address 
resolution, admission control, and subnet bandwidth management. 2. 
Telecommunications: H.323 entity on a LAN that provides address translation 
and control access to the LAN for H.323 terminals and gateways. The 
gatekeeper can provide other services to the H.323 terminals and gateways, 
such as bandwidth management and locating gateways. A gatekeeper maintains a 
registry of devices in the multimedia network. The devices register with the 
gatekeeper at startup and request admission to a call from the gatekeeper.

What I am trying to make is to change traffic communication between the two 
protocols (SIP and H.323). And I heard that is possible using a h.323 
component on the Asterisk. I'm using oh.323 component from Innaccessnetwork 
and until now I'm on the right way.

When it will finish I will post on the list the experience.
