[asterisk-users] Adtran feature codes, extensions

[Charles Ulrich]

Greetings,

We have An Adtran 616 Total Access device talking to a colocated 
Asterisk machine over MGCP. Calls placed to the phones connected to the 
Adtran go through as do outgoing calls from the phone (prefixed by 9), 
but feature access codes (*97 for voicemail, for example) and 
extension-to-extension calls don't work. As soon as the first digit is 
pressed, the user hears a busy signal. I confesss to not knowing much 
about how MGCP works, but I can't seem to find any kind of digit map in 
the Adtran so is Asterisk the one listening for but not acknowledging 
these digits? What do I have to do to make these work? Any help 
appreciated. Thanks!
