[Serusers] Adding +1 to From:/To: for E.164 compliance

Seems unreasonable to require From/To formatting, unfortunately,
at least one company I can think of does that.
Anyway, you will need to either properly format
the from/to at the origin (presumably the UAC) or
you will need a b2bua in the signal path to modify those
fields. Unfortunately, you CANNOT change anything in
the message EXCEPT the RURI. You can add information.
The From/To/Callid form a key for the message.
That said, you could change the From/To, and sometimes things
will continue to work because there are other 'keys' for the message.
But it would not be proper.
I don't believe vanilla SER will accomplish what you
desire. Perhaps you could put Asterisk in the signaling path?
