Re: [OpenSIPS-Users] Call continuity

[Mike Tesliuk]

This is the kind of structure where you need a BGP session with your
carriers, when you have an ASN and your own IP Block you can have your
communication flowing between any internet links you want, as the ip
address will flow between all of them, this is the right way.


if you have two simples internet connections there is no way to do that

Generally speaking, no, though the answer will vary with the modalities
of the failover mechanism.

But in general, failing anything over to another Internet connection
means changing the address of one of the endpoints involved. All
session-based Internet applications, whether using a
connection-orientated transport or not, presume that the IP and port
endpoints on both ends stay the same. 

So, if you suddenly start sending media from another place and expecting
to receive it there likewise, that will not be considered to be part of
the same phone call.

[OpenSIPS-Users] Call continuity

[Abdirahman A. Osman]

Hi Everyone,

This is a non-related OpenSIPS question, it is a SIP question.

I am not expert in SIP , so let me know what you guys think about this.

Is it possible to keep a live call continue , if the internet connection fails 
and route it through another internet connection ? Does SIP protocol support 
this kind of Call continuity?

Thanks

Abdirahman Osman
