Ive just managed to get hold of an SPA3102, and was wondering if someone who has a working unit could help me out here.

Ive managed to get the various NZ ring frequencies and cadences from

Ive managed to tweak the gain, impedances, etc. to get the FXS working really well.

However, I cannot seem to find the FXO/PSTN values anywhere. In particular:

Tip/Ring Voltage Adjust
Operational Loop Current Min
On-Hook Speed
Line-In-Use Voltage
Ring Frequency Min
Ring Frequency Max
Ring Validation Time
Ring Indication Delay
Ring Threshold
Current Limiting Enable
Ringer Impedance

Could someone post their settings please.
