The scheme is as follows: TDA -> SPA 3102 (FXS) -> Ethernet (Wi-Fi) -> SPA 2102 (FXO) -> Phone When you call - incoming work. Outgoing - long beep, and then short tones (busy). Please tell me where the error occurred. Thanks in advance. Sorry for my english (goolge translate)
The call from the SPA2102 to the SPA3102 fails. I would try this first: SPA3102 PSTN Line Tab Line-In-Use Voltage: 22 (change from 30) why: The INFO Tab shows PSTN Line Status Hook State: On Line Voltage: -30 (V) With Line Voltage 30v Line-In-Use Voltage 30v the SPA3102 would say PSTN Line Busy and would return busy. If you post Syslog again change: SPA3102 PSTN Line Tab SIP Debug Option: FULL SPA2102 Line 1 Tab SIP Debug Option: FULL Changes will produce more information about call. Only run SPA3102 or SPA2102 syslog during call, not both.
It seems the connection scheme is not correct or it's a typing mistake? You have to attach the SPA3102 via PSTN Line port ( it's FXO) and on the remote SPA3102 you have to use the Phone port to attach an analog phone (it's FXS). Maybe you have to switch the devices. Recently I have had similar problem and it's fixed by swapping the spa3102 devices.
