I use an ATA (Cisco SPA112). This is an analogue to digital converter basically. It has 2 analogue ports and an ethernet port. You configure it to use a SIP account on the extension programmed in the PBX it can then use analogue equipment (phones faxes etc). Voice seems OK but faxes are more prone to issues. I read mixed success rates online and was hoping I would find a setup that would work for me here. In Australia the Government are forcing a cutting of analogue services so we cannot keep an analogue line going.
Thanks again,
Joe
