We have an old 70 volt, 2 wire system with generic overhead speakers from 10+ years ago, and want to get this equipment working with Swicthvox.
We can get a 4-port FXS card and paging interface for about $500/site (we have 4 sites in different states, and each site has 5+ existing speakers) to make it work, but management thinks there might be a cheaper option.
Does anyone have a better cheaper solution ?
Maybe some type of adapter/converter ?
