Are you using MGCP on your gateway and perhaps ISDN L2/L3 backhauling?

I noticed also there was no "show isdn active call" etc etc type output when using isdn backhaul under MGCP.

Yeah, as I thought.

It seems that you do not get any "show isdn xx" output when your backhualing ISDN L2/L3 to CCM via MGCP.

Certain "show isdn active/history" commands state: "%Q.931 is backhauled to CCM MANAGER 0x0003 on DSL 0. Layer 3 output may not apply"

I'm guessing most likely because the CCM is controlling the D channel on the ISDN the gateway doesn't get to see much of it from a ISDN L3 perspective, probably because the CCM has its CDR's with which to track calls.

Yeah...this could be the reason that sh isdn active/history does not show any output...

Thanks a lot for help...
