[Asterisk-Users] Asterisk SIP phones to Cisco Unity via CCM4.0SIP Trunk

Tue Jan 24 13:16:54 MST 2006

Greg,

appending the number just gives me  a fast busy.

Mike,

a) is out because the cheaper cisco sccp phones don't have two way speaker
phone

b) is what I have, and are trying to get to work.  see my previous email
about the sip trunk.   I don't know what to do to make unity go into the
greeting for the user who was called.

c)  I'd like to, but I just switched voice mail for all my users, and I
don't want to endure the nightmare of switching again.  that's my long term
goal.
