PSTN Failover

[Andyd358]

Hi just quick question for you more knowlegeable folks.

Is it possible to have a PSTN failover fro a mulitenant hostes PBX. For example if the intenet connection goes down the phone can use a Grandstream or similar device to make an outside call? (My thought is no it cant but would love to know if its is possible)

Can it easily be done? Not if the pbx is hosted elsewhere and no SBC is on site.

Can it be done the hard way... sure with enough effort and/or hardware.
You could install a basic fusion instance on site with something like a Raspberry Pi or cheap PC and set phones to use it as a secondary
kludgey option could use direct IP dialing to an FXO gateway on a secondary account on phone
Etc
Etc.

The reason im asking is we currently have a few onsite PBX and these fail over to grandstream for PSTN at present this works well but we woudl like to move these to a hosted PBX but I am doubtful we can do it. We need to keep it really simple for the clients, they just need to be able to pick up a handset and make a call without having any additional steps.

If it already has an on site pbx, it would be pretty simple to duplicate settings on a cloud pbx and set the secondary proxy/sip server to fall back to local pbx.

Fair amount of work for you, but virtually invisible to the client.
