[cisco-voip] Difference between transfer and conference

[george.hendrix at l-3com.com]

Sounds like a codec issue to me as well.  Are the calls transferred back
out the same gateway?  Are there DSP transcoders available for the
gateways and phones and UCCX servers?  When you say transfer, is that
simply using their phone or the CCX application?

Subject: [cisco-voip] Difference between transfer and conference

 

as far as the call setup / call flow, what is the difference between a
transfer and conference.  Forgive me if someone answered before.

 

we have been having on going issues with telecommuters (IP communicator)
getting calls transfered to them from our operators.  

 

Call can be transfered and we get the call connected but no way audio
(sounds like a codec issue to me But it doesn't fail.... we have to hang
up) but doing the same thing with the conference button then dropping
off the call works fine.

 

had about 3-8 TAC cases open on this and still have the same issue.
much less, but still have the issue.

 

Call flow is call comes in PSTN via PRI / or CAS T1 on a 3845 running
15.0.1M3 (one TAC case had us add mgcp behavior g729-variants static-pt

mgcp behavior dynamically-change-codec-pt disable which helped a lot but
didn't fix the whole problem)

 

goes to UCCx agent (otherwise known as operator) who transfers to IP
Communicator (telecommuters).  The problem we still have is that
sometimes (2-10 times a day) we get the call transfered but there is no
audio.  But if they instead conference them in then exit the conference
it works.

 

other TAC cases we have open are for IP Communicator and are working on
upgrading all IPC users to 7.0.5.1.

 

What would a transfer do(or not do), that a conference call doesn't?

 

any comments / thoughts / answers appreciated.
