I use Soho66 as my small business voip provider. Recently my mobile phone provider has been switching us to IPv6 which apparently Soho66 cant support (only IPv4). I was therefore wondering if I could use Asterisk on a Linode cloud server to proxy the connection between Soho66 and my devices. If this is possible, what do I need from Soho66 to make this work? I’m a newbie when it comes to understanding SIP.
A proxy won’t help you as the communication channels will be negotiated and the transport will likely also be IPv6. A B2BUA (Back-to-back user agent - Wikipedia) like Asterisk can cope with something like that.
Would I personally do something like that? No, no, never. Far too risky as far as stability and maintenance is concerned.
