I thought maybe one of the providers here could answer this question. When using IAX to make calls, it passes the called number. Being designed to work with a PBX this makes sense. SIP works differently though and I'm curious why providers don't have a way to pass the called number on their DID's, or choose not to do so. Providers that themselves use upstream SIP proxies are obviously getting both the callerid and the called number. However all incoming calls I get to my DID's have the caller id as the SIP user being called.
I'm guessing that it takes using some additional SIP headers to get both called number and callerid, and that most providers probably don't want to have to support that for their clients. That's my very rough guess. Can anyone shed some light on the real reason?
