[asterisk-users] IAX & WaitExten

[Christian Stuellenberg]

Hello list,

I've got a problem (maybe only a problem of understanding how * works) with IAX and WaitExten.

To simplify the problem I've brought it down to the following scenario:

- 3 Asterisk Server A,B and C (central).
- A and B both register with C.

Now I want to be able to dial an extension at A to become connected to C and there I want to dial an extension to become connected to B.

I've done the (following) tests all in *CLI at ServerA, so that no other dtmf methods may have impact on the results:
> dial 161 at default
 --> connection with Zap/1 at server B can be established
> hangup

> dial 17 at default
 --> connection with server C established and waitexten waiting for input
> dial 161
 --> connection with Zap/1 at server B can be established
> hangup

So far so good, but:
> dial 16 at default
 --> connection with server B established and waitexten waiting for input
> dial 301
 --> nothing happens (either on server b nor c or even a) 
 --> timeout! 

Does asterisk at server C "eat" the extensions I dial, although they ought be send to B??

Thanks in advance for any help or hint towards a solution,
Christian
