1 Call = 1 session when call is direct
SBC is a back to back user agent. A single SBC call will crate 2 SIP sessions.
For licensing purposes Sangoma uses SBC Sessions to describe the session capacity.
Thus License of 500 sessions is equivalent to 500 SBC Sessions which translates to 500 end to end calls.
- Thus: 1 Session is equal to 1 Call.
- Registrations and other SIP messages are not counted as part of license capacity.
- This makes the licensing and scaling of Sangoma SBC’s really simple and intuitive.
