[cisco-voip] Difference between transfer and conference

[Scott Voll]

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.
