I thought so too, but it doesn't appear to .
I just bought a door intercom device, set up the extension for it and
it's doing the same thing, when it connects there is a 10 second delay
before the other side can hear my voice.
However watching tcpdump, the audio starts streaming both ways immediately.
Changing the dialplan fixes the issue:
957 => { // Test door phone
Answer(); // <--- this line fixes the problem!
Dial(SIP/199,20);
Hangup();
};
It's an ok workaround for the door intercom, but in the case of the
forwarded calls below, as soon as I Answer() their ringback disappears
and the line goes dead while they wait for our guy to answer the phone.
I may start a separate post about getting ringback to work after Answer();
Thanks for the help by the way.
