Summary:                    SIP RTP audio delay
Description: 
This is *not* a latency issue.

This is a very very odd issue, when a caller comes in through two asterisk
boxes via SIP the IVR is heard fine, but when transferred from the IVR the
caller and the person being called experience about 2-3 seconds of silence
before audio begins to flow.

This has been reported numerous times across the net but no real solution,
some examples are:

sadly there isn't much debug here, a packet capture shows RTP flowing etc
the same in both circumstances, please advise.
