Delayed call processing for numbers dialed to area codes 306 and 587

[birnit]

We are using CUCM 8.6 and are experiencing issues with call processing delays for numbers dialed to the area codes 306 and 587.  We are located in area code 780.   We dial a 9, then 1 for long distance plus the 10 digits and can experience up to a 23 second delay before we hear ringing.   This is not consistent for all 306 and 587 numbers.  We have not been able to narrow it down to specific NXX's.      Any tips on what direction to take our troubleshooting efforts?

I'd start by looking at CUCM dial plan for any kind of overlapping, then some GW debugs to find out if there's any delay in the signaling there.

Hi Birnit,

It seems that you are facing an issue of " Call Setup Delay" and this issue generally comes from the remote end.

Please take a trace / debug and  note down the following points:

1). Call setup message time

2). Call proceeding received time.

3). Alerting message receive time.

If you find the difference between " Call Proceeding" & "Alerting Time" then it means that the remote or destination end is taking long time for processing the destination or called party number .

If such the case then check the internal trace of remote end and just see how many tables it passes through.

Final if everything is OK from the remote end then please check for any bandwidth issue.

Thank you

Nishant
