H323 and CCM 4.1(3)

Unanswered Question

we are note getting a stable connection at call initialization. We hear one ring on our end, then the call dies. about 30-40 secs later it rings again and we can answer the call. all of the callers say there is dead silence when they dial, they think the call didn't go through, so then hang up and try a second time.

This site has only FXO ports and is running H.323


any ideas ?

thank you

Check h323 bind command in GW,

In CCM check proper IP address...

Any firewall in between ?

Make sure dial-peers and plar commands are configured properly, can you attach your config and debug voice ccapi ino and debug vpm signal

I thought about the bind command too.

I'm not sure if we have a firewall, I will have to confirm that

I'm attaching the config with the debug output

Hola Cris,

The outgoing dial-peer is 2

the incoming one is the 900


In CCM for that GW and IP Phone which region is configured? GW should be announcing both

G711 or G729

Cal disconnection is 16 normal call clearing

Can you disable G722 codec and send me also CCM detailed trace?


Thanks

most probably goga refers to the enterprise parameter:


Advertise G.722 Codec
