Maybe this depends on the protocol, if so, I'm wondering mostly about SIP.

That's all, just focus on the title please, but for a little background...

I am using voipraider and I was just trying to set it up to have a caller id as my phone number, since I can't have this voip of mine on all the time (thus using DID or being able to receive calls through voip wouldn't be a solution here).

I could actually make it work, but only using voipraider software. From other places, the caller ID doesn't show properly. So, I am wondering how it actually works to be able to go and look for a fix for this.

I want details about the protocol, if that's relevant.
