[cisco-voip] Dropped calls coming from FXO

Could you complete a debug dial peer to determine which dial peers you
are hitting. It may be that you are grabbing another port instead of the
voip dial peer.

Hi, i have a ccm 6.0 who has 2 h323 gateways configured.
One of them has one E1 and works fine
The other one, is a 2811 with 1 vic2-2fxo card and has 2 FCTs attached.

A specific route pattern on CUCM sends calls to Company's Mobiles
through 2811- This direction works fine!
But, an incoming call to FCT, only rings the specified DN!!
For example, i have a connection plar on the voice-port to send all
calls to 2000 (console).
When someone calls FCT, 2000 rings once and then the call is dropped!!
The amazing is a few times it works fine!! (most of the times it
doesn't)

I have used *... because the Telephone Company (mobile) uses *XXX for
calls between its subscribers.

In CUCM, there is *XXX route-pattern pointing to this voice gateway.

Any ideas? It seems really bizarre that a few times it does work!!

i also provide the voip ccapi debug of a failed call as attachment.
Thanks Akoul
