Take a look at the replace method in the textops module
http://www.iptel.org/ser/doc/modules/html/textops.html
You could do something like:
replace("^To: <sip:", "To: acct# <sip:");

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
