I have this command configured. One thing i found out yesterday is that it apparently happens when all parties are internal also. So no trunk involved.

Personally I haven't experienced this in my testing. It was 2-3 seconds for audio to establish which i thought was ok. The customet had said they timed it to be 8-9 seconds.</p>

I might have to do a wireshark and see if there are retransmissions for signalling.

<div dir="ltr" class="gmail_msg">This sounds like the old too-many-messages-are-required-to-make-the-transfer-happen scenario. Ok, I just made up that name, but basically the SIP messages are just busy doing whatever SIP messages do, to make the transfer happen. From stopping
media, to invoke MOH, to tearing down MOH, to transferring, to establishing media, it's just a lot, and takes a long time.
