This really isn't my "field of expertise," but nobody else is chiming in. 
Will the following help?

; test for availability
         exten = _5xxx,1,                verbose(1,Testing for availability)
         exten = _5xxx,n,                chanisavail(sip/${EXTEN})
         exten = _5xxx,n,                verbose(${AVAILCHAN})
         exten = _5xxx,n,                verbose(${AVAILORIGCHAN})
         exten = _5xxx,n,                verbose(${AVAILSTATUS})
         exten = _5xxx,n,                voicemail(${EXTEN}@default,u)
         exten = _5xxx,103,              playback(pbx-invalid)
         exten = _5xxx,n,                hangup

If you took an "AGI/database" approach, you wouldn't be constrained to 
"the extension is numeric and has to match the stanza in sip.conf" and 
would allow more features like a web page to "check-in" or whatever.

Thanks in advance,
