I was fortunate that there is plenty of information for configuring an
SPA3000 & SPA3102 for my country.
Perhaps page 53 of this document
may help, the other parameter I needed to adjust to receive Caller ID
was the 'PSTN Answer Delay' setting.
I can't recall any great pain setting up an HT-503, I suspect I based
settings upon an SPA3102/SPA8800, the T.38 faxing on the FXO was
successful after a Firmware Upgrade, it was a couple of years ago when I
was setting this up.
