Summary:                    wrong SRV query
Description: 
asterisk (chan_sip) generates wrong service records queries to dns.
it queries to _sip._UNKNOWN.foo.bar, instead of _sip._udp.foo.bar
if this first query fails, it try second query srv by appending asterisk
server dns domain to previous query, eg. _sip._UNKNOWN.foo.bar.domain.com,
third try is to query A record for foo.bar 
I think this "automatic" failover is unnecessary or even incorrect,
causing needless delays

I found some incorrect memory handling in enum.c, 
when invoke ENUMLOOKUP() function, I got following warnings in mmlog:
WARNING: Freeing unused memory at (nil), in ast_get_enum of enum.c, line
897
WARNING: Freeing unused memory at (nil), in ast_get_enum of enum.c, line

it's probably not directly related to this issue, 
so tell me, if I should open separate bugreport or if it's so trivial,
that can be fixed immediatelly.
