asterisk users - Feb 2006 - Re: Will not authenticate incoming VOIP provider

I don't use digitalvoice, but based on a similar provider you may need to
have your username inserted
in your extensions.conf context....

[incoming_calls]
exten => username,1,Answer( )
exten => username,2,Playback(demo-echotest)
exten => username,3,Hangup( )


Just an idea....
