My house has an Orenco Septic system with a VCOM-AXA panel for remote monitoring via a phone line. When I bought the house, the phone line was never connected. I don’t want to pay for a landline just for monitoring this system so instead got a Grandstream 801 along with voip.ms service and was able to get it connected. I noticed the panel is making calls out on a regular basis, but all calls are reported as failed by voip.ms.
It looks like this panel isn’t actually making regular phone calls but instead has a modem. Does anyone know if analog modem over VOIP with voip.ms is supported, and if so what specific settings (codec, etc ) should I use on my Grandview ?
