<div>Hi Justin,</div>
<div> </div>
<div>thanks for your answer. The command "isdn global-disconnect" did the trick.</div>
<div> </div>
<div>Thanks for helping!</div>

<br/>
I am trying to setup a QSIG over SIP connection between a CUCM and a IOS TDM<br/>
Gateway. Calls are working so far. But when an IP-Phone tries to end a call<br/>
it seems to be that the signaling from CUCM to the Gateway is not understood<br/>
by the Gateway.<br/>
<br/>
When I hang up on the IP-Phone the CUCM sends some SIP INFO packets and<br/>
after 20-30 sec CUCM actually sends a SIP BYE message to Gateway. I captured<br/>
the SIP Traffic between the CUCM and the Gateway and I saw in Wireshark that<br/>
there are DISCONNECT messages in the QSIG over SIP INFO packets. I assume<br/>
these DISCONNECT messages are not correctly understood by the Gateway. The<br/>
Gateway only ends the call when the CUCM sends a SIP BYE Message.<br/>
<br/>
I have tried CUCM Version 8.6.2 and 9.1.2 and some IOS 12.4 and 15.2<br/>
Versions.<br/>
<br/>
Regarding my configuration:<br/>
<br/>
Enabled ISO QSIG on SIP Trunk pointing to the Gateway<br/>
Defined switch-type primary-qsig<br/>
Defined qsig decode under voice service voip<br/>
Configured signaling forward unconditional under voice service voip and also<br/>
on the dial-peers<br/>
<br/>
So, my questions are:<br/>
<br/>
Should QSIG over SIP work between CUCM and a IOS Gateway?<br/>
Can anybody provide some working sample configurations? (Could not find<br/>
anything useful on CCO)<br/>
<br/>
<br/>
Just for completeness, I have attached the relevant Debug output.<br/>
<br/>
<br/>
Thanks in advance,<br/>
<br/>
Robert<br/>
