[SR-Users] Active calls limit

[Daniel-Constantin Mierla]

Hello,

the avps are available only for the duration of a transaction. They
don't persist between register and invite. But you should authenticate
invites as well, not only registrations, and then the avp will be loaded
and set for invites.

Cheers,
Daniel
