Title: SIP Trunk Delays when answering
Post by: gpatchev on July 20, 2010, 05:08:17 PM

We have Exchange and OCS integrated with our 3300s.

The only little bug I see is that when answering calls I have about a 4 second delay before I can hear the other person spleaking.

The same applies for the exchange sip trunk. When the call is transfered to exchange there is a few second delay before you hear the exchange auto attendant speaking.

Is there a setting to tell Mitel 3300 to immediatly connect the call?

Thanks.

That is an interesting problem.  Anything logged on the OCS or Exchange event logs - or the 3300's for that matter?  Have you done a sniffer trace.  Sip is pretty easy to decode....

The logs in OCS look clean.

An OCS to OCS call is instant.

I do notice that when I answer the call it indicates in OCS that the call is on hold for a few seconds prior to me hearing the person on the other end.

Would you recommend wireshark to debug this or the OCS logging?

  Interesting - is supervised transfer enabled somewhere causing this.  Just thinking out loud here...
