[asterisk-users] Questions about SIP From, P-Asserted-Id fields and Diversion headers ?

[Olivier]

Hi,

After a long discussion with a friend, I would like to ask here:

1.According SIP RFCs, is possible/recommended to have different values in
>From and P-Asserted-Id fields ?
For instance, From field showing 123456789 and P-Asserted-Id showing
987654321 (beside privacy considerations) ?

2. When Bob forwards to Cory a call coming from Alice, would expect
Diversion/History-Info header to include Alice's number ?

Best regards
