I think the reason is because the telephony equipment of your telco is still analog.
(In belgium it was the same, until they started replacing all the old stuff with fancy digital things.).

Hi,
 in Spain that process is correct. If you setup a communication between
a caller and a called, if called phone hangs, in caller side hear a
silence, but is a correct process. It's is due to in the called side you
can hangup a phone and pickup other phone without lost communication.

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


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
