asterisk users - May 2005 - AT-320 + supervised transfer

Hi all, 
I'm trying attended transfer on Asterisk 1.0.7 and AT-320 phone. I met a
lot of problems during this steps, while in the blind transfer all works
fine.
I had this kind of problem:
 
CASE 1:
    A call B
    B set on hold A
    B call C (that is busy for some reason)
    B try to get the first call with "hook flash" (or pressing the
"hold" key) and A stop to work. B stay waiting with an hung call with
C
without have the possibility to re-take it
 
CASE 2:
    A call B 
    B set pn hold A
    B call C (that is busy for some reason)
    B is talking with C 
    B has need to speak again with A, so press the "hold" key. At this
point A and C is frozen and B stay waiting with an hung call lost
somewhere
 
Another problem that i found, is that just i switch on the phone, i
can't make and receive any call until (the phone seem too slow to boot).
I have to "pick up" and "pick down" the handset
 
I contatted the chip's productor and he said me that my server
(Asterisk) doesn't have the re-invite. The only thingh that i can do is
to set "canreinvite = yes" in my sip.conf
 
Anyone can help me please? Anyone never had a problem similar to mine ?
 
Thanks for all
 
Giordano

Hi,

1.0.7 does not support atxfer. You nees to use CVS. I have a bunch of the ATCOM
cheapos and only CVS will take notice of 'atxfer' in features.conf.

Otherwise , consider this scenario...

Call comes in, press HOLD, dial other party to see if they wish to speak to the
caller. If so, press * to hang up, then HOLD to swap back to the incoming
caller. Announce you are going to transfer them, and now dial the final
extension and press FWD to do a blind transfer.

This works for me with the SIP 1.43 firmware. The IAX fw still has some way to
go...

The phone seems slow to boot? Ensure you have the IP/hostname of a valid NTP
time server at the bottom of the web config page. If you don't, it will take
ages and eventually fall back on 'time.windows.com'

Cheers,
Gavin
