My application is an IVR that is supposed to handle multiple numbers like (1234, 4321 etc.). The IT guys insist that I pick up the call because they say that a SIP UA can have multiple accounts (they are the ones who gave me the sipua1 account credentials). I on the other hand persist that its not supposed to come to me because I didn’t register with these URI.

I’m confused now, because for one, I can not look up any text that explains the difference between a SIP UA and an Account. Plus I don’t know what the standard way is to handle such a situation. It would be easy for me to pick up the call, but I can easily have two UA’s and then the situation would become more drastic, because then how would I tell which UA’s supposed to handle it.

Any insight would be great.
