Problems with AS5300

Dear friends :

Sometimes our AS5300 shows the next message on the log : %SCHED-2-EDISMSCRIT: Critical/high priority process ISDN L2D SRQ Process may not dismiss.At this moment the active voice calls are lost.

Any idea to solve this problem ?

Thanks .

Re: Problems with AS5300

Often times complex troubleshooting issues are best addressed in an interactive 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.
