  Dear all,
  
  I stumbled upon the following thread in the Office Communicator forums, while researching an issue we have with forwarding of calls.  I thought it could be interesting to share it here as well:

  When a call comes in from a telephone line that does not send caller ID, the AutoAttendent refuses to forward the call to an extension. The SIP trace reveals the error "Cannot process routing destination" and shows that the phone context is "'dialplan.domain.com@10.0.0.200 (10.0.0.200 = Front end server IP address)".   When the caller does transmit his/her caller ID, the phone context is different and the forwarding works.
  
  Thanks for your assistance,
  Best Regards
  Wim
