[OpenSIPS-Users] [OpenSIPS-Devel] Fwd: RTPproxy project

[ag at ag-projects.com]

Regarding high availability. I admit that in ten years of deployments I have never heard a single customer asking for this. They were rather asking for having multiple relays in multiple data centers because losing one IP was in most cases associated with complete connectivity failure to that data centre and a single IP failover was something that even if possible the costs far exceeded the benefits. A single IP address going down out of a larger connectivity issue context is such a rare occurrence, practically I don’t remember ever hearing a customer complaining about such a thing.

In my opinion addressing new features like what rtp engine solves with regards to interoperability in more real time scenarios is a smarter investment rather than optimising in places were the benefits can be hardly measurable. Not to mention that the term "carrier-grade” like its predecessor "five times 9 availability" is slowly exiting the vocabulary and is being replaced with webRTC ready and other newer concepts.

My two cents

With MediaProxy one can shutdown gracefully a relay by allowing it to carry on finishing existing calls and then shutdown while the traffic is handled by other relays. This way one can upgrade the software on a relay farm without dropping a single call.
