Good day,

Does anyone know how exactly FS handles Sofia gateway configured with the following?

• proxy resolved through DNS SRV; returns 5 records of the same weight
  
• registration disabled
• SIP OPTIONS enabled

Is it going to send OPTIONS to 5 IPs in round-robin?

If so, what if 2 out 5 fail OPTIONS but the rest remain active? Is FS going to intelligently round-robin calls between remaining 3 IPs or it will mark the entire gateway as "down"?

Thank you,
-Victor
