I’ve got 1 SIP phone (Aastra) and 1 Sangoma Analog card with 2 port FXS and 2 port FXO cards in it.

I’ve got it so that my SIP phone can call the analog one fine, and conversations can be made. But trying to call from the analog phone asterisk immediately hangs up on the Zap channel. Verbose output when trying this isn’t really helpful:-

Any ideas anybody, I’ve googled and searched the forums but got nowhere with it ;(

Sorry - cut a different version of the zapata.conf (tried a lot of fiddling): it should read internal, not incoming. (I get different error, complaining about a non-existant context with incoming in it!)
