ISDN not working
Hello

I am working on an ISDN connection, but having problems for last 2 months, and I have been shuttling between CISCO , and my ISDN providers.

This list form name seems to discuss cisco issues, hopefully I have not subscribed to wrong list.
Here is my problem If call from cisco router one side of ISDN to other side USR I-modem on my network this is what I see

From cisco to USR with q931 debug enabled

CisNwsMry#isdn call interface bri0/0 17326490191
CisNwsMry#
6d12h: ISDN BR0/0: TX -> SETUP pd = 8 callref = 0x18
6d12h: Bearer Capability i = 0x8890
6d12h: Channel ID i = 0x83
6d12h: Keypad Facility i = '17326490191'
6d12h: ISDN BR0/0: RX <- CALL_PROC pd = 8 callref = 0x98
6d12h: Channel ID i = 0x89
6d12h: ISDN BR0/0: RX <- DISCONNECT pd = 8 callref = 0x98
6d12h: Cause i = 0x849F - Normal, unspecified
6d12h: Signal i = 0x03 - Network congestion tone on
6d12h: ISDN BR0/0: TX -> RELEASE pd = 8 callref = 0x18
6d12h: ISDN BR0/0: RX <- RELEASE_COMP pd = 8 callref = 0x98

This is what I see when I dila into cisco from USR

6d12h: ISDN BR0/0: RX <- SETUP pd = 8 callref = 0x79
6d12h: Bearer Capability i = 0x9090A2

Locking Shift to Codeset 5
6d12h: Codeset 5 IE 0x2A i = 0x808001, 'P'

I have changed calling called numbers so that is not issue in case some people might hint on wrong number more than 10 or 11 digits.

Any help will be appreciated.
