ms-office-communicator

I am using Microsoft Office Communicator with a USB headset as my work phone. OCS is connected to our PABX so we can take and make calls to regular, non-OCS phones. When making an external call to a cellphone, it can take up to 5-10 seconds for audio to start flowing.

eg:

Work Phone                  Cellphone
- dial cellphone
  (ringing)                 (ringing)
                            answer cellphone
  (hearing nothing)         speak "1"
   .                        speak "2"
   .                        speak "3"
   .                        ...
   .                        speak "14"
  hear "15"                 speak "15"
  hear "16"                 speak "16"

Has anyone experienced this kind of thing with an OCS setup? Any pointers?

My company recently mandated a switch from Skype to Office Communicator for IM / voice chat. While Skype was never the be all and end all of VOIP, it was at least usable.
