Hangup behavior different between the received incoming and

Asterisk Asterisk Support
1

Hello.

Hangup behavior different between the received incoming and outgoing calls.

I do not know if this is a configuration error or a bug in dahdi driver

If a incomming call to asterisk is answerd adn then only th asterisk juser hangs up the line will stay up until the external party do hangoup.

If an outgoing call from asterisk is answerd and then only the asterisk user hangs up the line is auto disconnected.

The switch is placed in sweden. Reverse polarity for answer and hangup.

Asterisk version is 1.6.2.18
Dahdi version is. 2.4.1.2

This is intended network behaviour for the UK phone network at least for landline calls on simple lines. I imagine it is intended behaviour in other countries as well.

Normally you need ISDN type access to to be able to force a release and achieve a called party clear. For simple lines, only the calling party can release the call. (It is also possible that earth start lines, intended for PABX use, will also have called party clearing.)

The reason it is done this way is so that the called party can put down one phone and then pick up another phone on the same line, without losing the call.

Is there any posibillity to change the behaviour. We don’t wont asterisk to keep the line open, hangup directly is prefered.

I did try to change to ground start, and the dahdi driver did not load.

Running dahdi_cfg: DAHDI_CHANCONFIG failed on channel 1: Invalid argument (22)
Selected signaling not supported
Possible causes:
FXS signaling is being used on a FXS interface (use a FXO signaling variant)
RBS signaling is being used on a E1 CCS span
Signaling is being assigned to channel 16 of an E1 CAS span

You need to talk to your PTT. Even ground start is primarily a change at their end, although it does require a suitable line card at your end.

You need to ask them if they are able to enable called party clearing on your lines. If not, you will probably have to switch to ISDN digital presentation.

NB I don’t have the experience to guarantee that even that will help.
