I recently moved a client from one provider to another. Specifically from VoIP.ms to Twilio.
With VoIP.ms, even if I use PJSIP as my trunk, their signalling does not do anything different than if I use a SIP trunk as it relates to Caller ID.
But with Twilio, when I set up the PJSIP trunk, the caller ID as shown on the desk phones is totally different. This confused users.

What can I do about the ringing version from Twilio? Personally, I like the extra information (
From Num: and
Via:). The users though, do not. They want the Caller ID resolved name (I use Superfecta) on a line by itself and the number on the next line while ringing. With the extra data, that is all shoved up on one line and has to scroll.
