[asterisk-users] Strange problem with zap channel.

[Tim Uckun]

I am trying to help a guy out with his Atcom IP04.  He has set it up like this.

He has a handful of IP phones all connecting via SIP. He has two phone
lines connected to the FXO ports one from telecom, another from
vodaphone.  He has set up the dialplan so that one of the trunks fails
over to the other trunk.  Everything seems to be working OK except for
outgoing calls.  He can call from extension to extension without
problems. If I call in on either of the trunk lines we can have a
normal conversation.

If he calls out to me he can hear me but I can't hear him.  The status
on GUI shows the phone as still ringing even though I picked up and he
can hear me.

Here is a log of one of the calls.   If anybody can offer a clue as to
what the problem might be I'd be grateful.  I looked at the port
definitions and they are set up for NZ signaling (kewl loop).

At this point I have picked up the phone and am speaking, he can hear
me but I can't hear him.

After I hang up I get this.
