[asterisk-users] Transfer a call without announce : no sound

[Nicolas Ross]

When we receive a call from outside (via a sangoma 104d card) and we do a
"blind transfer", that is without anouncing to the called party , we have no
sound either way.

Exemple :

I take my cell phone to call my * box, it rings on my aastra 9113i phone, I
answer.
Then I hit the xfer buton, make my second call to another extention (it can
be either a aastra phone, nortel phone trough ciel portico, whatever.
As soon it rings I hangup or hit the xfer buton again.
Then the bridged call between the other extension and the zap channel have
no sound either way.

If I wait for the called party to answer and announce the transfer, all is
fine.

I've had report of sound one way also, but I wasn't able to reproduce.

Here's the log from my console :

   -- SIP/224-09e0f098 answered Zap/1-1

Any ideas ?
