[Freeswitch-users] B leg ringing when Caller hangup before answer

[Charles Wang]

Hi all,

I have a server with freeswitch 1.4.15 + freetdm(FXS/FXO). I think there is
a bug in inbound call via the freetdm FXO device.

When I try to make call from FXO and it bridges to SIP device named 1234
via the following dialplan.

 <extension name="my call test">
                <condition field="destination_number" expression="^(1234)$">
                        <action application="set" data="call_timeout=30"/>
                        <action application="bridge" data="user/1234"/>
                 </condition>
   </extension>

Before SIP 1234 answers the call, the caller (FXO) hangup call before 1234
answered. But the callee (SIP 1234) is still ringing and stop ring after
about 30 seconds.

It is the same condition if the callee is FXS device.

I can find two channels during ringing (A leg & B leg).
After the caller(FXO) onhook, the A leg is still alive and A leg will not
be hangup before the callee (FXS or SIP) stop ring ( call-timeout ).

There are two legs (A leg & B leg) after the caller FXO had hangup.
