[Freeswitch-users] Sofia regiter to provider with multiple account

[Dome Charoenyost]

Dear All,
        How to config freeswitch for support this case ?
     1. FS register to provider about 50 user account. (Each account
can't support multiple call in same time)
     2. FS Check account not inuse before call out.
     3. User account should be round-robin
