Far end disconnect using ISDN

Hi,

I am using ISDN, on initiating the call I am getting following error, it appears like the call is initiated for a while (1 or 2 secs) and then hangs up with message "Normal call clearing".

Any suggestions as why this problem is occuring.

Aug 6 08:58:59.037 UTC: ISDN Se1/0:23 Q931: RX <- CONNECT pd = 8 callref = 0x96C4

Aug 6 08:58:59.049 UTC: %DIALER-6-BIND: Interface Se1/0:21 bound to profile Di21

Aug 6 08:58:59.049 UTC: %ISDN-6-CONNECT: Interface Serial1/0:21 is now connected to 0667723420 N/A

Aug 6 08:58:59.053 UTC: ISDN Se1/0:23 Q931: TX -> CONNECT_ACK pd = 8 callref = 0x16C4

Aug 6 08:58:59.213 UTC: ISDN Se1/0:23 Q931: TX -> DISCONNECT pd = 8 callref = 0x16C4

Cause i = 0x8090 - Normal call clearing

Aug 6 08:58:59.313 UTC: ISDN Se1/0:23 Q931: RX <- RELEASE pd = 8 callref = 0x96C4

Thanks

Yamin

Re: Far end disconnect using ISDN

Hello Yamin,

have you got any isdn caller command on your PRI or Di21 that can filter 0667723420 N/A ?

the N/A makes me think that your router doesn't recognize the number as part of a numbering plane and for this reason disconnects.

Also

Note: The following printout indicates a higher-protocol failure:

Cause i = 0x8090 - Normal call clearing

PPP authentication failure is a typical reason. Turn on debug ppp negotiation and debug ppp authentication before assuming that the connection failure is necessarily an ISDN problem.

Hope to help

Giuseppe

Re: Far end disconnect using ISDN

Hello Giuseppe,

Yes it is the authentication failure, I just fixed it and it is working fine.

Appreciate your reply.

Thank you

Yamin
