MS Office Communicator: Long delays in setting up audio connection when starting a call

  • 772

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?

  1. I'd be really interested to know what happens when you run the OCS pre-call diagnostic tool (http://blogs.technet.com/brettjo/archive/2009/09/20/ocs-pre-call-diagnostic-tool.aspx) before placing a call. This sounds to me like you're having a latency problem.
