[VoIP] Status and other information

[Andrew Green]

If you have host=dynamic that means anyone that has that user's
username and password can register that sip account from any IP
address. The only reason it would come up as OK is if there is
something actively registering and using that account. Unknown means
something has registered but asterisk doesnt know if it is or not, and
unmonitored means that nothing has registered with that SIP user and
pass. When its 'unspecified' it means you have no registration on that
user with host=dynamic in that user context in sip.conf. That was
probably incoherent but it should help a bit :)
