I have configured my SPA3102 to handle CID on PSTN line. In our country the standard is ETSI FSK + V23. Everything is working fine - during a few calls or on first day. After that the 'Private caller' string is displayed on the phone, no caller id displayed on WEB information screen. If I switch off and on the device (SPA3102), the CID is displayed again during a few calls.
I use the latest firmware (5.1.10).
I hope, someone can help me.
