We currently have an integration with Lync 2010 and a Cisco Cups.

Call control and presence are working fine, however it seems the Incoming Caller ID is not being passed to Lync.  We can see the caller id on the Phone, but receive "Anonymous Caller is Calling you" on the Lync Toast.

Any ideas what I can check to troubleshoot this?

hi - most likely, the client is receiving the called ID in a format it cannot recognise.

exactly what caller ID format are you seeing on the phone?

I recommend you enable logging on the lync client, reproduce and examine the logs with the Snooper tool.

Hi,

Please make sure you have the normalization rule which converts the user's telephone number field from AD into the E.164 format.

Are you referring to a Dial Plan Normalization rule or the "Company_Phone_Number_Normalization_rules.txt" file?
