[asterisk-users] Asterisk not hanging up calls

[Simon Tennant]

I have noticed that Asterisk (version 1.2.13) is not hanging up a call
when the wifi handset moves out of range.

My setup is Nokia E61 connected to wifi access point (private IP range)
and then to server on internet (public IP).

I have been testing using the talking clock application, and walking out
of range does not hang up the call.

The call will continue for hours even though the handset re-registers on
another access point 5 minutes later with a different public IP.

Subsequent calls continue fine although I still see traffic heading out
to the old public IP address of the wifi access point.

I thought the SIP control channel would do some kind of keeping state
and time out a call after "x" number of failed replies.

I know there is a timeout option but would rather not set a timeout on
all calls.

Here's the sip.conf that I am using for the device:
