<tt>Hi all,<br>
i have a ccm ip network and a voip gateway which is connected with an
alcatel PBX with isdn Q-SIG.<br>
When i call an alcatel extension from the ip phone, i get no alerting
tone on the IPphone, although the alcatel phone is ringing (here is the
debugging of the isdn q931)<br>

<font color="#330033">I know it has something to do with the progress
indicator (there is none in the first call) but do i have to fix it on
the gateway or it has somenthing to do with the PBX?</font><br>
