[cisco-voip] No alerting tone on voip gateway

[Anthony Kouloglou]

Hi all,
i have a ccm ip network and a voip gateway which is connected with an 
alcatel PBX with isdn Q-SIG.
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)

callref = 0x0031


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?

Thanks

Anthony
