[SR-Users] Accessing indexed header PV from app_lua module in Kamailio

[Daniel-Constantin Mierla]

Hello,

it seems there was an issue fixed by Ovidiu Sas -- in git master so far:

http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=8b9a98e8a8205b2214bf3503afea8aece20e2396

Can you try that patch and tell if works for you?

Cheers,
Daniel
