hi guys,
caught in a strange senario where in ISDN connection works fine for sometime and then once the call is terminated it doesn't come up automatically next time.
I have to force the bri interface to reset
The problem seems to be at layer - 2 which goes to TEI_ASSGINED state and i am not able to make a test call but when i reset the interface it goes to State = MULTIPLE_FRAME_ESTABLISHED and this time i am in position to make a test call
bottom line is every time the ISDN link is not working i have ro reset it manually to make it work.
I have also attached my ISDN router Config file with output of SHOW ISDN STATUS n debug isdn q931

Which router / IOS is this ?
Can you upgrade IOS to like latest 12.4 and try again ?
Also configure "isdn tei-negotiation preserve", that could help.

Thanks for mailing my friend,
IOS is already 12.4 and we tried "isdn tei-negotiation preserve" but its still not working.

Which exact version of 12.4 are you using ?
