Hi fulks

I try changing info value in PAI header-field by using subst() function into route block as below:

route[3]
{
        ...
        $var(fromU) = 22227777;
        ...
        subst('/^P-Asserted-Identity:(.*)sip:[^@]*@([a-zA-Z0-9.:]+)(.*)$/P-Asserted-Identity:\1sip:$var(fromU)@\2\3/ig');
        ...
        ...
        forward();
        exit;
}

But when I read ngrep command output I catch P-Asserted-Identity header as below:

+++++++++++++++++++++++++++++++++++++++++++++++
before route[3] processing:
INVITE sip:99992222@15.113.132.21:5060 SIP/2.0.
...
P-Asserted-Identity: "Display Name 7777" <sip:7777@101.14.101.245>.
...

+++++++++++++++++++++++++++++++++++++++++++++++
after route[3] processing:
INVITE sip:99992222@15.113.132.21:5060 SIP/2.0.
...
P-Asserted-Identity: "Display Name 7777" <sip:22227777@101.14.101.245>.P-Asserted-Identity: "Display Name 7777" <sip:7777@101.14.101.245>.
...
+++++++++++++++++++++++++++++++++++++++++++++++

So, is it normal or bug behaviors?

Regards

CMA
