[c-nsp] Call rejeciton from Cisco

On a related note, I am aware that part of the problem might be that the called party number might be listed as plan unknown and type unknown. I've been trying to figure out a way on the IAD 2400 to set this to national and isdn for all outgoing calls, but the only way I can find to do that is with translation rules, and those all seem to assume that the first thing you want to do is search and replace part of the dialed number. I really don't care what the dialed number is. Is there some way to match just on the plan and type, or some way to set those values other than a translation rule?

  Hello. I am using an AS5400 to generate a PRI that is then going to a CiscoIAD. So on the AS5400 side I have. The IAD only has 8 analog voice ports, so I am using the last 8 channels of the PRI for voice ports, and the first 16 channels as a T1 for internet service.

  controller T1 1/0:24
   framing esf
   channel-group 0 timeslots 1-16 speed 64
   loopback network ignore
   pri-group timeslots 17-24

  interface Serial1/0:24:0
   ip address 216.24.28.249 255.255.255.252
   encapsulation ppp
   no cdp enable
  !
  interface Serial1/0:24:23
   no ip address
   isdn switch-type primary-ni
   isdn protocol-emulate network
   no isdn outgoing ie redirecting-number
   no isdn incoming alerting add-PI
   no cdp enable


  On the IAD I have....

  controller T1 1/0
  framing esf
  linecode b8zs
  channel-group 0 timeslots 1-16 speed 64
  pri-group timeslots 17-24 nfas_d primary nfas_int 1 nfas_group 1

  interface Serial1/0:0
  ip address 216.24.28.250 255.255.255.252
  encapsulation ppp
  !
  interface Serial1/0:23
  no ip address
  isdn switch-type primary-ni
  isdn incoming-voice voice
  no cdp enable

  dial-peer voice 1 pots
  description route calls to ISDN
  destination-pattern .T
  port 1/0:23

  The PRI and TEI's seem to be up. The AS5400 has intermachine trunks connecting it to the telco system and routes incoming and outgoing phone calls all day long, but when I try to make an outgoing call from the Cisco IAD I see the IAD 2400 appear to do the call setup and send the call out 1/0:23, but eventually I get a reject with a cause code of "0x0", which isn't very helpful. I'm not even sure if the error message is coming from the far end (the AS5400) or the near end (the IAD2400).

  Error output below with the reject highlighted in red. It would seem that the called is being rejected for "Invalid information element contents." I'm having a hard time determining which elements it considers invalid, though. We've never generated our own PRI out to a client box before, so any information anyone has would be greatly appreciated. Also, if anyone has a config example of both ends of such an arrangement I would love to see it.
