All inbound calls are represented as "UNKNOWN" on my TA410 analog FXO gateway, it does not show caller ID at all.Does anyone have the same problem ?How to resolve this?? I am using 3CX as PBX.

  You need to know 3 different pieces of info  - 

  1. Does the telephone service provide callerID? (some may charge extra for it and if not subscribed to, it will not be provided). 

  2. Is the callerID detection set correctly in the TA device for the telephone provider? 

  3. Is 3CX set to look for the CID info sent from the TA in the correct SIP header? 

  As 3CX has an Ethernet capture capability, you can capture a incoming call and see in which header the CID info resides (or not) and then set 3CX inbound parameters to look for the CID in the header which contains same.

  Well analog gateway pass it to 3cx as uknown so i guess no need to check on that ? Call is marked as UNKNOWN on analog gateway call log.
