check the line supervision signalling of your GSM and the GXW4104. there are several disconnect signalling used: current disconnect, polarity reversal or busy tones. your FXO port must be set accordingly. <br><br><div class="gmail_quote">

Hi<br>
<br>
I have successfully managed to get FreeSwitch to bridge an incoming call<br>
on a PSTN line to an external mobile phone using a second PSTN line with<br>
the help of a GXW4104 FSO gateway.<br>
<br>
I am now having a serious issue where the call never gets terminated<br>
when the parties hang up. The only way to end the call is to either<br>
shut-down FreeSwitch or turn off the GXW4104. If I bridge the call to a<br>
SIP gateway (PennyTel) instead of the second PSTN line, then it works as<br>
expected when both parties hang up.<br>
<br>
Here is what I have tested<br>
<br>
1. Call -> PSTN line1 (GXW4140) -> PennyTel SIP gateway -> external<br>
mobile phone -- call end when both parties hang up.<br>
2. Call -> PSTN line1 (GXW4104) -> PSTN line2 (GXW4104) -> external<br>
mobile phone -- call never end, even when both parties hang up.<br>
<br>
Is there a parameter I should be setting to help solve this issue or<br>
some code that I should implement to test for this situation?<br>
<br>
I have also noticed that with test scenario 1 (PSTN line + SIP Gateway),<br>
if the person being called does not end the call on their side, then<br>
that leg of the bridge remains active.<br>
<br>
ps. The second PSTN line is not a real copper line. It is a PennyTel<br>
VOIP line that is managed by the modem and connected to the GXW4104 via<br>
phone cable. So, as far as the GXW4104 is concerned, it is just another<br>
POTS line. I don't have a second PSTN phone line so can't test any other<br>
way.<br>
<br>
Thanks in advance<br>
O.<br>
