Connect a phone with a display through the FXS port
and let the PSTN line to "ring through" to the VOIP. 
That way you can check do you receive callerid at all.
You could play with the delay secs untill you are sure
you see a callerid(probably only number).
And most probably the callerid method should be ETSI.

Any experience with as how a GSM CLIP is read by 
spa3000? Anyone?
