Up front: Call routing has as such nothing to do with SIP registration.

Look at qualify= for sip.conf, and consider to extend your diaplan for a 
better routing decision with a snippet like this:

exten => _00.,n,Set(VOIPCHECK=0)
exten => _00.,n,NoOp(-- ${PEERCHECK1} status: 
${SIPPEER(${PEERCHECK1}:status)} --)
exten => _00.,n,ExecIf($["${SIPPEER(${PEERCHECK1}:status):0:2}" = 
"OK"]|Set|VOIPCHECK=1)

where PEERCHECK1 corresponds to the provider section in sip.conf that you 
would like to monitor.
