Hi, Some ATAs (SPA3102, M-ATA, ...) have a long local FXS settings list such as : FXS port gain, Ring Waveform Frequency ... 1. My understanding of these is that those settings define how calls coming from SIP side, trigger a signal which will in turn, ring analog device. is this correct ? 2. Are those values local for each country ? 3. Shall I change them according the analog device plugged into the ATA ? 4. Then, where can appropriate values be found ?
