It's a bad idea because they are used for transaction matching and if you alter either then you run the risk of a SIP UAC or SIP UAS freaking out.

I also have two providers using the to header.
Why is it a bad idea to modify the to and from fields?

Our VoIP service provider routes calls based upon the To field within the SIP header. While SER can easily rewrite the URI, I need to actually prepend our account code to every outgoing call with a prefix. does anyone know how to prefix the To field.
