CM 3.2.2c H323 PRI ISDN DMS100 gateway. Q.931 Disconnect cause code 0x8AFF indicates PSTN returning error from a network beyond the internetworking point. Anyone experienced anything like this? Thanks.

I think what may be happening is it gets passed to lucent switch for cellular then goes SS& to mobile, Lucent I believe needs to see calling party as national for it to get mapped correctly to ISUP.

Try putting this on serial interface 3/0:23 as a test

isdn map addr . plan isdn type nat

okay its private network serving remote user, interworking unspecified cause.

is what kind of gateway ? is gateway connected to switch or pbx ? can I see

debug isdn q931 from setup to disconnect ?

usually you see this when you go gateway to gateway and one side is setup to a pbx running qsig ( which is vendor dependent)and the other is a standard such as dms or ni2. You see it when the qsig side does a facility or a shift to codest that the other side can't map into the standard stack.

3660 nm-hdv-2t1 MFT h.323 gw connected to siemens pbx using ISDN DMS100. New CIPT implementation using new DID range 604-676-XXXX. I'm wondering if the remote cellular service provider serving 416-821 and 822 does not recognize 604-676 DID range?
