Re: Catalyst 4224 Problem

Often times complex troubleshooting issues are best addressed in an interactive trouble-shooting session with one of our trained technical assistance engineers. While other forum users may be able to help, it’s often difficult to do so for this type of issue.

To utilize the resources at our Technical Assistance Center, please visit and to open a case with one of our TAC engineers, visit

If anyone else in the forum has some advice, please reply to this thread.

Thank you for posting.

Re: Catalyst 4224 Problem

Try getting a debug isdn q931 for a call that works and a call that does not work and see if you can tell what the differences are. Sometimes when you send all the digits other countries think you are doing overlap sending. Are you sending all the digits at once? Do you get a setup_ack back from the telco?

Thank you,
