[cisco-voip] CFwdALL failing for calls originating outside CCM

[MILLS, Mark]

Hi,

I have an issue with CCM where CFwdALL does not work for calls
originating over a Q.SIG trunk to our Ericsson MD110, but does for all
local CCM attached phones.

For example, I set my extension (7702) to forward to voicemail (8890).
Any other VoIP user is correctly transferred to the Voicemail system.
If a call comes in over the Q.SIG trunk (Ericsson user or PSTN user),
the call is not diverted to voicemail, instead the user is given an
engaged signal... It does look like it tries to transfer the call to the
Voicemail system, but fails.

Any suggestions on what could be the cause of this would be very very
helpful, or at least where I could be looking.

The basic setup:

  PSTN ----> MD110 ----QSIG----> 1700Rtr ----MGCP---> CCM

Cheers,
  Mark
