Right. Anything coming over SIP the system knows it's a SIP call. It'll just accept whatever is being passed on SIP calls and only do lookups on actual calls coming in from numbers.

So say someone used a softphone to call your SIP address and they had a "Name" field set in that, that should be passed on and used.

If someone uses that same softphone with the name set to call your phone number, it would do a lookup in the CNAM database to get the Caller ID for them ignoring the Name field.
