[OpenSIPS-Users] Need help on flag in usrloc

[Bogdan-Andrei Iancu]

Hi Ha,

the two flags are different and may have different values - one is used 
as NAT marker, the other one is used as SIP-based pinging marker.

so, you can use different flags and both of them will be saved in cflag 
mask.

Regards,
Bogdan
