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

13 Dec 2005

Normally I would call a statement like:

If (uri=^sip:123456@somewhere.com)
	{
	..do something
	}

I would like to implement a dial plan using the "From:" header.

i.e.: 
If (from_uri=^sip:123456@somewhere.com)
	{
	..do something
	}

Anyone know if something like this exists?
