The From header field in a SIP message is used to identify the initiator of the
request.
AFAIK, the 05099999999 in the From header acts as a display name. It can be used to
determine the processing rules by other SIP entities. For example, PSTN gateways can
use
it to determine if it is a valid callerid or not (For INVITEs). The Auth credentials in
the Request can be different. It should be the username and password for the account
that
the provider has given you. I hope others here will give a better explanation on
this...

I think yes. Our UACs register with SIP Express Router with different values in these
fields. Attached below is an ngrep trace of such a request processing.

Sorry. I am not sure about this.
