[OpenSIPS-Users] methods= from register contact

[Bogdan-Andrei Iancu]

Hi Dani,

Actually the lookup() function has an "m" flag to do "method filtering" 
- if the current method you are doing lookup for does not exists in the 
method bitmask of the record, the record is considered not matching. See :
     http://www.opensips.org/html/docs/modules/1.7.x/registrar.html#id292848
    - about the "m" flag
    - about the "-2" return code.

Regards,
Bogdan
