I am attempting to setup a peer to peer in this order: PSTN > HT503>LAN>HT801. MY HT503 is located behind the router with the PSTN plugged in the “LAN” port of the HT503. If someone calls the phone number to the PSTN hooked up to HT503, it rings once and they get a dial tone. On the HT801 side (4 miles away - linked by Ubiquiti transmitters), when I dial out, there is total silence for a while then after a minute get a fast busy signal.
I set this system up using instructions found on the net “How to extend connection to a remote site” - Peer to Peer Handy Tone Scenario
Note, I am not using a SIP server just wanting to extend a PTSN line using my LAN Any recommendations
