Hello List.

I have created a patch some time ago, to use the ISDN feature "call deflection" or partial rerouting, as it Is also known, to make proper call transfers on PRI, without using an extra channel for the outgoing call.

Back then I ported the function zapCD from bristuff, to a normal zaptel, and it worked as it should.
I am looking at this again, and was wondering if anybody has made a similar function for zaptel, since this is a very usefull feature, or if I should make a new patch myself.
Kind Regards
Jon Leren Sch?pzinsky

I recall that this is now part of Asterisk (1.4 or 1.6 or both). It
really is a great feature rather than using two channels in "trunk to
trunk" transfer.

Thanks,
Steve Totaro

This is often called a "Two B-Channel Transfer", or TBCT. As long as
your PRI provider has this service enabled on your PRI, recent versions
of libpri, zaptel, and Asterisk will support this. Obviously it won't
work if your PRI provider hasn't enabled TBCT on your PRI.

On the Asterisk side of things, you need to make sure you have
"facilityenable=yes" and "transfer=yes" in zapata.conf for the bearer
channels of your PRI.

Actually this isnt the same as Two B-Channel transfer.
This is done by sending a FACILITY message to the ISDN, which in hand then disconnects the call and sends it to the number provided in the call deflection message.
All b-channels are closed when the FACILITY message is sent.
You can also send a deflection reason code, such as Busy and Unavailable.

Now to come up with a way to "busy" out individual channels via this
or another method. This is one feature that is in great demand.

Thanks,

Do you mean individual B-channels?

That could be done in dialplan, with the ZapCD command... When its done that is Smile
