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

[Greg Oliver]

You can have asterisk dial your Unity vmail pilot on busy or
unavailable, and have CCM use the last redirected number on the trunk to
determine the called extension, or pass the $RDNIS value and digit
add/strip from * to CCM.

We use * in the exact opposite fashion, but should suffice either
direction.
