[Serusers] How can I change dial rulesbased on From:' headerinstead of R-RURI?

[Leo]

Dear Iqbal &  sip at arcdiv,

Thank you for the excellent input.

I like the idea of using groups since it seems very simple. I could also
write a CRON job that updates the groups table based on who is presently
registered in the registration table. This way the group table will also
represent who is registered. This will allow me to NOT route at all unless
the from: header is registered. 

By the way, I do have control over the endpoints. While I can't guarantee
that no one is "spoofing" the "From:" header, this is good enough for now.

I am hesitant with AVP's because I know very little about them, however,
they do look very popular. I need to figure out how I can learn them a
little better. I have been to the AVP website at Voice Systems, but it seems
to be geared towards OPENSER and I am not using that presently. I am still
on SER 0.9.4 and I plan on staying there for the near future.

Leo P.

true...but then if remote users, i.e interconnect with other voip 
providers, better to use trusted tables I think...opinions
