I have a FreePBX server running in my house, currently with a couple of PCI FXO cards in it and I would like to replace that power hungry computer with a lower power consumption device like a Mac Mini or similar and utilize an external FXO device to bring my phone lines into FreePBX/Asterisk.
While I utilize external SIP providers I do need at least one FXO for my Xfinity voice line.
I don’t know that macOS can be used for the PBX but that’s not a big deal, I can just use the standard distro instead but the big thing is wanting to add an external FXO adapter since the mini doesn’t have PCI slots.
I read the writeup on the Grandstream 410x devices and that looks to be a cheap way to do it but hate losing call waiting as a result, but if this is the only way to go without spending a fortune then maybe that is what I need to consider.
Any advice on what I might use for FXO that doesn’t require an internal card is appreciated.
