Hello,

I received INVITE with 3 Diversion headers. 
I try to make substitutions in the body of a first Diversion header field by using flag "f",

command subst_hf("Diversion", /sip:(.*)@/sip:$var(dU)@/", "f") ;
substitutes all headers Diversion instead of only first header,

command subst_hf("Diversion", /sip:(.*)@/sip:$var(dU)@/", "l") ;
substitutes  only last Diversion header.

Thanks for help,
Julia.
