[Asterisk-Users] Zaptel doesn't see remote hangup ? euro-isdn

[Robinson Tim-W10277]

This is quite common in some countries.  Analogue lines are some times
configured for 'calling party clearing', where an inbound call to an
analogue line will hold the line for some minutes before timing out.

Might this explain the behaviour?

Hi

Just received my spanky new TE405P today to replace my Cisco gateway...

After much fiddling (I forgot to switch it to E1) I got it to work and 
everything "seems" to work perfectly on our ISDN PRI.

If I dial-in from the PSTN to a SIP phone, the call goes through and if
I 
hangup either the SIP phone or the remote end, the call gets
disconnected 
and destroyed

However, if I dial-in from the SIP phone to my PSTN and then hang up my
PSTN 
phone, the call does not get disconnected. My SIP phone goes quiet but 
doesn't disconnect. If I a few seconds later pick up the PSTN phone
again, 
the connection is still there. Only if I hangup the SIP phone, the call
gets 
destroyed. It seems that Zap doesn't see the remote hangup...

Here is my Zaptel config and my Zapata config. I presume the extensions 
config etc are OK as my call-flow never changed and things were working
fine 
with my AS5300.

Am I missing something ?  How do I debug the Zap channels ?

Cheers,
Walter Klomp
