We were having phantom calls as well. In our case, we had 2 pots line
running in our sangoma card, and when you dial out, would would wait
for whomever to pickup. If you gave up waiting an hung the phone up (we
also had 2 normal phones plugged into fxs ports), it wouldn't
immediately receive the hangup signal. The call would connect, then
asterisk would turn around and try to call us back. If the other side
hungup because they just heard dead error, then when you'd repickup
your call, it would also be dead air.<br>

Not sure if this is the same case as yours, but ours was odd as well.<br>

they answer the phone, there is only silence and then they hang back up
and it sometimes rings again.
I've been trying to track this down for a couple of weeks now with no
success yet. If anyone can lend a suggestion or a pointer to look for,
I would greatly appreciate it.
I've tried using WaitForRing() in case it is bad signaling coming from
the phone company. But that has not helped.

<pre wrap="">I highly doubt this is the cause. I suspect a dialplan error.
Ask your client if they are doing anything else when this happens, like
making a fax call ;)

Thanks for responding, Stephen.
The client has a fax line, but it is separate line from the Asterisk
box. They have 3 lines coming in. 1 goes directly to fax machine and 2
go to Asterisk box.
I've searched the archives and "phantom ringing" comes up a few times
without any real resolutions that I can see.
The only thing very different about this installation is that the
customer has no intermediate IVR. They want the phones to ring directly
to a group and if no answer, then go to a mini IVR that asks if they
would like to hold longer or leave a message.
The "device" calling on CallerID when this happens is the default
CallerID set in sip.conf Device <callernum> which was never changed.
That was changed to a correct value. It appears as though the system is
calling itself.
