I have used the Patton FXO AND FXS gateways to bring analog lines into FreeSWITCH with success, but their programming requires a 4 year college degree to figure out! The Patton gateways will detect call progress tones as well as loop battery interrupt to know that the FXO has released the call and will process that correctly to tell FS to end the call. Thanks for your experience as switching to something else might be better, instead of testing different scenarios.

I use analog card named TDM400P and there are two FXS and two FXO on it. You can find it from this url http://www.ryu.com.tw/image/A400P.jpg. There is a white power outlet behind it.

It sounds like your originating caller is analog and is not providing supervision signal to indicate to the FXO port that it has released the call, therefore FS continues as if the call is still held active.
In some configurations the loop battery is interrupted briefly to indicate that the call has been released. In other cases you must detect call progress tones that indicate that the caller is no longer present. In some cases there is no indication provided to the FXO port and only timers and the Leg B will help you.

Hi Brian,
I ever try to answer the A leg in dialplan before bridge to B leg. But the condition is the same.
B leg is still ringing after I hangup the FXO.
I notice that the ringing of B leg will stop if the inbound tdm leg is FXS.
Let me know if you have any suggestion.
Best regards,
Charles

You may wish to answer that inbound tdm leg before ringing out to the sip device.

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.
