[asterisk-users] strange behaviour of a zaptel device

[Thomas Artner]

Hi!

I am working hard on getting a useful attented transfer. (The built-in
atxfer feature isnt useful - because of calls getting lost - has been
discussed a few months ago)

I have all my analog phones on sipura boxes. With the flash hook i can
do such attended transfers without problems now.

But, the asterisk box is connected to a POTS line via a digium card. And
here I have a strange behaviour:

.) a call comes in (via the digium card)
.) Person A takes the call (on a sipura pap or spa device)
.) Person A presses the flash button and dials an other extension for
Person B
.) Person B hooks the phone off (sipura pap or spa), talks a few words
with Person A
.) Person A hooks the phone on.
.) the incoming call is transferred to Person B, BUT the caller on the
incoming call cant hear Person B, while Person B can hear the incoming
caller!


Does anyone have any hints for me ?  Asterisk at log level 10 doesnt
show anything... :-(


thx in advance,
Tom
