Withhold number does not go through After-hours

[Babak KHorshid]

HI All, 

I am trying to understand CUCM and new to this but I have this issue which I have no idea where to even look. I wonder if you guys can give me some steps to narrow down the issue 

If members call 0X XXXX YYYY after 5:00PM on their mobile phone which has their number withheld. Then the call does not go through to the After-Hours Number to our IT Technicians. If the withhold is off then no problem! 

technically call wont go through if the calling ID is hidden. 

Is there a setting to change this behaviour ? 

Regards

Some questions for you:

• What version of CUCM are you running?
• How is the call arriving at your site (PSTN SIP trunk, ISDN, etc.)? And how is that connected to CUCM (SIP trunk, MGCP, H323)?
• Is the call flowing through Unity Connection as an after-hours auto-attendant, or does the call come straight to CUCM?
• Do you have any other time-of-day routing in your system?
• How are the calls getting to the after-hours IT staff? (Single Number Reach, CUC call handler? UCCX? etc.?)

There is a checkbox on CUCM trunks to Reject Anonymous Calls, but if the behavior is different during the day and after hours then that checkbox would only take effect if calls are pathed differently based on time of day.

Something else you can take a look at is the Dialed Number Analyzer. In DNA you can have it analyze an inbound trunk call and add time of day to the analysis. That may provide some clue of CUCM's thinking on how the call is being processed.

Let us know more about your system and I'm sure we can figure out what is going on.
