[cisco-nas] Call rejeciton from Cisco

[Joseph Mays]

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.
