Summary:                    [patch] atxfer broken on 1.6.2.11
Description: 
I'm using SIP phones.

- A calls B
- B transfers A to C by pressing ?2, then C's extension (atxfer =>
https://issues.asterisk.org/view.php?id=2 in
features.conf)
- C picks up, talks to B.
- B hangs up.
- both A and C hear silence

afaict, A is not bridged to C. This issue was not present in 1.6.1

---------------------------------------------------------------------- 
FWIW, We are getting the same type of results when transferring between
Polycom 650's using the transfer button (no DTMF transfers).  Does not
happen on every transfer, but the results are always the same in that the
sound is inaudible or silent.
Most transfers are from an agent in a queue transferring the caller to
another extension.
Running Asterisk-1.6.2.11 under EL5 with latest Kernel with chan_sip and
chan_local.
Polycom phones are running sip 3.1.3.
