[Asterisk-Users] Asterisk SIP phones to Cisco Unity via CCM 4.0SIP Trunk

[sys read]

I have my eyes on the Linksys/Sipura 941, ( SIP ), but the core problem is
that you can't use SIP phones with CCM.  I have a SIP trunk between asterisk
and ccm.  I can route calls back and forth, I just can't get the call to
send to vm if no answer on the asterisk side.
