May also be worth checking that your Sipura has the latest firmware
installed, and perhaps installing ngrep on the asterisk box so you can
track what's going on with the SIP packets.

I've been doing some work recently coding up a VoIP->PSTN switch that
accepts calls from both Asterisk and SIP Express Router and do sometimes
see this sort of problem, but not regularly enough to be able to track
down the cause.  It feels like somehow the SPA2000 registration is being
forgotten about, but I can't see why.
