DNS/VoIP gurus -- If a DNS provider supports SIP SRV records, but 
doesn't support NAPTR records, would SIP service be affected by a lack 
of the missing NAPTR records? E.g. 
http://en.wikipedia.org/wiki/NAPTR_record#Example

According to rfc 2915 ... "In the case of NAPTR, the actual domain-name 
is specified by the various fields in the NAPTR record. In this case the 
client isn't asking a question but is instead attempting to get at 
information that it has been told exists in an SRV record at that 
particular domain-name."

So it all depends on what URI the client is presented with in the first 
place? In other words tel:+14235551212 isn't the same as sip:+14235551212?
