Any advantage to using FWD and Asterisk? Bart Fisher 08-09-2006

I answer incoming phone calls for a client located in NY, I'm in
California. If a caller desires to talk to NY, How would be the best
method to so.

1. Have NY register on my Asterisk Server and handle the call directly
2. Have NY register on FWD and have Asterisk send calls to NY using
another FWD extension from my location.

I'm mainly trying to conserve bandwidth (we have a full T1, NY has DSL
at 128 K). But more importantly create reliable connections to NY.
Also, FWD offers some nice features I wouldn't have to manage on my
server if they were in the middle.

Any ideas on this would be helpful

3. Setup asterisk and the phones to be able to do SIP reinvites. Then
transfer the call's data stream to NY if the caller wants to talk
to NY directly.

Thanks Wolfgang - I finally got a chance to read about how
'canreinvite' works.

If I understand correctly, it will allow asterisk to setup connections
enabling the endpoints to talk directly, bypassing asterisk resources.

The part that wasn't clear is, would asterisk still be able to create
a CDR for a total call duration or for only the duration asterisk was
involved in the call?

You're welcome. Asterisk still stays in the loop as far as the SIP
signaling goes. SIP does the call setup / tear-down. The only thing
that goes direct is the voice RTP data. So yes, the CDR is still for
the whole call.

BTW. With reinvites you can transfer the call back and forth as many
times as you want and the data still gets sent directly with no
"looped" data stream.
