[asterisk-users] Call parking and RTP traffic

[Dave Fullerton]

Greetings

I've noticed something odd while messing around with a test system and 
I'm not sure if this is a bug or not. I have three phones connected to 
an asterisk system in a remote office over a point to point T1 (no nat) 
all set up with canreinvite=yes. The phones are a Polycom 601, 501 and a 
budgetone 102. Here's what I am seeing:

Phone A calls phone B, phone B answers. RTP traffic travels between A 
and B directly like it is supposed to. Phone B does an attended transfer 
(using the phone's transfer features) to the parking extension, waits 
for the parked number and then completes the transfer. RTP travels from 
phone A to asterisk and hold music is played like it is supposed to. 
Now, phone B calls the parked extension and the call is reconnected, 
except the RTP traffic is now traveling A <-> Asterisk <-> B. I would 
have thought traffic should resume going between A and B directly. Is 
this an incorrect assumption or is it a bug?

I've tested this on 1.2.11 and SVN-branch-1.2-r41989.

Thanks
