- No internet - no phones : this is an issue in that we don't have redundancy on our network link, but there has not been any network outage since the fiber was installed at this particular site several years ago. Not sure what I can do on this short of say we could keep a POTS line or two for emergencies but that of course starts to eat into the cost savings some also.
Maybe you can setup a 4G link as redundancy instead. Voip traffic doesn't require that much bandwidth so even if you only get 2 Megabit/s or something it is still plenty.
I would suggest against this - a lot of the 4G carriers do crazy things with NAT that SIP Trunks really really do not like. We run into CGN problems all the time:
https://en.wikipedia.org/wiki/Carrier-grade_NAT. It also can create issues with UDP Fragmentation.But if you are using a hosted PBX is that really an issue?
You can mitigate it somewhat, but yea, its still an issue. The best way to get around it with a hosted PBX is to use a VPN between the phone and the PBX. That will bypass most of the NAT issues and keep the phones routing the way they should. You can still get dropped calls though.
