[OpenSIPS-Users] Virtual Service Activation Codes

[Bogdan-Andrei Iancu]

Hi Indiver,

in a similar manner, when a user receives a call (somewhere before doing 
lookup(location) for the user ), you need to check a group to see if the 
user has (or not) the DND activated. If it is on, you can to redirect to 
VM or return busy indication.

Regards,
BOgdan
