@markosjal Get this idea out of your head right now. It’s not going to happen anytime soon. The version of ASterisk that is being used for this is a FORK which means it’s not an official release from Digium (Asterisk maintainers/developers) so that means FreePBX is not going to support it as it uses official Asterisk releases.
At this time Digium has no plans to incorporate this. As well, if they are going to then Nafg needs to clean up his patches to meet Digium standards and even then it is still up to Digium is merge those patches into the core.
Let’s also not forget, Polycom buys Obihai then Obihai releases new OBITalks with GV branding on them followed by Google actively tearing down the XMPP connections they say have been dying for the last 3+ years AND THEN announce they have a SIP based platform which is completely branded with Obihai. This isn’t a setup that screams “Oh yeah, we’ll let any ole device connect to our branded platform that we spent a lot of money on”. So there is no guarantees this is going to be the correct solution.
Let’s be clear on this GVSIP in Asterisk, more importantly FreePBX, is a hack/kludge solution. It requires an unofficial release of Asterisk and a non-Distro install of FreePBX. That alone now makes official support no longer viable from Sangoma. It also means that there is no support for the commercial modules such as System Admin. Without System Admin you cannot activate the PBX. No ability to activate no support, no commercial modules and no way to install modules that depend on System Admin like the System Firewall.
At this point if you are doing anything at a business level the idea of GV+FreePBX is no longer viable. You are better off sucking it up and getting a real ITSP/voice service because it will be less cost in the long run vs the time spent trying to make this kludge work properly or dealing with the downtime when either GV makes another change or a new update is released and causes issues.
