Hi Everyone,
can anyone advise a way around an issue I have. I cannot call Hunt Pilots with phones that are withholding their CLI. There doesn't appear to be an option within the Hunt Pilot configuration to accept/reject "Anonymous Calls" as there is with Directory Number configurations.
I don't think calling Hunt Pilots whilst withholding CLI is an unreasonable thing to want to do so I'm sure there must be an easy solution to this ? This is CUCM 10.5
Many thanks,
Matt

Hi Matt,
Is it possible members of your Line Groups all have "Reject anonymous calls" set on their DN? This could explain what you're seeing. I've noticed in one version of CUCM 10.5 that if you add lines with a Universal Line Template then that's turned on by default.

Hello,
What is the call flow for calls with no caller id (Anonymous)?

Hi Mohit,
it's a direct call from an IP phone to the Hunt Pilot. The IP Phone has a Calling Party Transformation applied that strips the Calling Party Number as detailed below:
Phone DN = 53112345
Calling Party Transformation Pattern = 531XXXXX. in Partition "Block_531_CLI"
Transformation Details = Discard "PreDot".
The Partition is assigned to CSS "531_Caller_ID_Blocking" and this CSS is applied to the "Calling Party Transformation CSS" field in the "Number Presentation Transformation" field on the Device config page.
Calling the Hunt Pilot with the CSS applied causes the call to be rejected due to Caller ID = anonymous. Removing the CSS allows the call to proceed.

Hi Jonathon,
that's what it turned out to be. Very frustrating default setting in the Univeral Line Template...
