[Asterisk-Users] Gatekeeper registration failed

[Juanjo Portela]

Dear friends,

I have compiled and installed h.323 in my asterisk. And I have a
service from a H.323 VoIP provider who give me user, password and
gatekeeper IP address.
All configured.

But when I start my asterisk i receive the following error and h.323
calls can not be making and/or receiving.

[chan_h323.so]=> (The NuFone Network's Open H.323 Channel Driver)
