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

[Walter Klomp]

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
