Asterisk is open to every kind of configuration. It has no embedded multi
tenancy but a lots of configuration were developed with multi tenancy in
mind. I know very little about OpenSIP so I am not the right source of info
about it. I never find the need of using something different from asterisk
from 2004 when I start using it.

As far I know it, you need a license for every active channel.
