[asterisk-users] IAX-Voicemail

[Andrea Bencini]

I have asterisk 1.2.18
Each my extention number has a mailbox; I have SIP extentions and IAX 
extentions.

When  I call an unregister extention number (SIP/IAX) from SIP 
hard/soft-phone, asterisk actives the voicemail (I can put a message in the 
mailbox).

Instead when I call an unregister extention number (SIP/IAX) from IAX 
hard/soft-phone I get an immediate hangup.

Can you help me
thank
Andrea
