[OpenSER-Users] Forwarding to SRV records not working

Hi, I'm having problems with OpenSER forwarding calls to a domain where there are only SRV records. OpenSER seems not to perform any balancing or failover when a target server is unavailable or gives an error. I wish to forward calls to a number of onward gateways that at times may not respond at all, or may respond with something like "503 Service Unavailable". The actual destination address is derived from an enum lookup, but it may be for example 123456(a)example.com There are SRV records as follows: _sip._udp.example.com. 600 IN SRV 10 50 5060 gw1.example.com. _sip._udp.example.com. 600 IN SRV 10 50 5060 gw2.example.com. The behaviour I'd expect/like would be that OpenSER will distribute the calls between the two targets specified in the SRV records, and will fail over to the other target if one fails to respond or gives a fatal error such as a 503. What actually happens, is that the calls all go to the first one regardless. Are my expectations reasonable? Does OpenSER's SRV record implementation work like this or am I misled? Kind regards, James
