hi all,
the new draft ieft-draft-sip-srv-02.txt says in step 3 as below
"If the DNS server returns no address records, the client
 gives up. If there are address records, the same rules as
 in step 2 apply."

in step 3 when we get the ip addresss of the server from DNS A RR,
how can we determine the protocol if it doesn`t exist in Request-URI?  Accorging to bis we should try UDP first and then try TCP.but this draft said we should use the same rules as in step 2, does it mean we still need to query the DNS SRV record?

thanks in advance.
