[OpenSIPS-Devel] drop a packet before the start of routing call: openSIPS

[Bogdan-Andrei Iancu]

Hello,

Please keep the mailing list as CC'ed.

there is no such function in 1.7, but try to use an error_route in your
script to catch and remove bogus messages asap - see
        http://www.opensips.org/Documentation/Script-Routes-1-7#toc5
