Happy New Year 2022 Everyone. Wish you a lot of innovation this year!
I was just curious to know if any of us had handled the mid-call failures using the Kamailio. I am writing a SIP Client to handle the failures by using the DNS SRV based failover and Fallback approach where I am using two Kamailio instances as Outbound Proxy resolved by DNS SRV lookup. Everything is fine except for on-going calls. How to handle the mid-call failovers? Is there any way in Kamailio like Call Preservation mode or something?
The SIP standards document setting up a call successfully with DNS support - NAPTR and SRV. But mid-call failover is not specified anywhere. There are some hints in RFC 3263 on using SRV names in route headers that could be interesting.
/O
Any suggestions or ideas to handle midcall failover so that if a current Outbound Proxy goes down then all the ongoing calls can be seamlessly routed through another Kamailio (secondary).
