[OpenSIPS-Users] trying to use the drouting module

[Bogdan-Andrei Iancu]

Hello Mark,

Your script does not handle sequential request (like BYE) at all. I
would strongly suggest to follow this webinar
http://www.opensips.org/Documentation/Webinars#toc12 in order to
understand the record routing and loose routing mechanisms in SIP. After
that, you need to change your script accordingly (you can check the
default opensips script - the part with the loose_route() function ).
