Issue with BRI dialup

I am configuring a BRI dialup.

Everything works fine when I test locally dialing from one SPID to the other but when I try to dial anything else I get:

00:57:37: BR0/3/0 DDR: Dialing cause ip (s=XXX.XXX.XXX.XXX, d=XXX.XXX.XXX.XXX)

00:57:37: BR0/3/0 DDR: Attempting to dial XXXXXXXXXXX

00:57:38: BRI0/3/0: wait for isdn carrier timeout, call id=0x804A

00:57:38: DDR: Dialing failed, 1 packets unqueued and discarded

00:57:43: BR0/3/0 DDR: rotor dialout [best] least recent failure is also most recent failure

00:57:43: BR0/3/0 DDR: rotor dialout [best] also has most recent failure

00:57:43: BR0/3/0 DDR: rotor dialout [best]

BRI and dialer configurations:

interface BRI0/3/0

Issue with BRI dialup

Can you run debug for ISDN Q931 while you attempt the call and post the output?

Issue with BRI dialup

Debug for ISDN Q931 below

00:51:28: ISDN BR0/3/0 Q931: Sending SETUP  callref = 0x0001 callID = 0x8001 switch = basic-ni interface = User

00:51:28: ISDN BR0/3/0 Q931: TX -> SETUP pd = 8  callref = 0x01

    Bearer Capability i = 0x8890

        Standard = CCITT

        Transfer Capability = Unrestricted Digital

        Transfer Mode = Circuit

        Transfer Rate = 64 kbit/s

    Channel ID i = 0x83

        Preferred, Any B-channel

    Keypad Facility i = 'XXXXXXXXXXX'

00:51:28: ISDN BR0/3/0 Q931: RX <- CALL_PROC pd = 8  callref = 0x81

    Channel ID i = 0x89

        Exclusive, B1

    Locking Shift to Codeset 5

    Codeset 5 IE 0x2A  i = 0x80880B, 'XXXXXXXXXXX', 0x800109800114800114800114

00:51:29: ISDN BR0/3/0 Q931: RX <- DISCONNECT pd = 8  callref = 0x81

    Cause i = 0x82C1 - Bearer capability not implemented

00:51:29: ISDN BR0/3/0 Q931: TX -> RELEASE pd = 8  callref = 0x01

00:51:29: ISDN BR0/3/0 Q931: RX <- RELEASE_COMP pd = 8  callref = 0x81

Issue with BRI dialup

Thanks for providing the debug output. I believe that it does help us understand the issue. The key item is this line

Cause i = 0x82C1 - Bearer capability not implemented

When I look up the code 0x82C1 I find this explanation:

The network cannot provide the bearer capability that the user                requests.              Contact the telco to troubleshoot further.

So it looks to me like the ISDN circuit is not provisioned the way that you think it is. You should check with your provider about how the circuit is set up.
