I was talking about *incoming* calls from the PSTN to the FXO port on
the Sipura-3000. The SPA pick up the call coming in from the PSTN and
returns a fast busy to the PSTN caller then hangs up.

Outgoing calls from Asterisk via the SPA to the PSTN work fine.

On incoming calls, the SPA makes no attempt to send the call anywhere,
so it's not a SIP issue.

thanks anyway
