subst() textops bug? - sr-dev

10 Jul 2017


      I try replace info PAI header by using subst() function in 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.
...
+++++++++++++++++++++++++++++++++++++++++++++++
Is it normal or bug behaviors?
