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
