[Asterisk-Users] how does a sip://user@dom.ain url come in

[Randy Bush]

if the dns has

   _sip._tcp.my.dom.   SRV     0 0 5060 asterisk.dom.ain.
   _sip._udp.my.dom.   SRV     0 0 5060 asterisk.dom.ain.

where asterisk.dom.ain. is an A RR of the asterisk pbx.

how does a call to sip://user@my.dom come in to asterisk
so i can route it?

do i just put in sip.conf
