[Users] Hijack 'Move Temporarily'

Hey Bogdan,

Thanks for replying.
Can you help me check my statement ?

avp_printf("i:678","$di");
uac_replace_from("$avp(i:678)");

I am trying to replace the FROM hdr using the URI in Diversion hdr.

It ends up as NULL when the SIP packet was mangled. Looks like $di is
empty.

Regards,
Sam

Hi Sam,

what hdr you need to extract the uri from? maybe there are pseudo
variables available and you do not need to use regexp.
For example, you have $di for diversion URI. See:

_header_uri

bogdan
