I got the ENUM lookup to work but the syntax of the NAPTR is not accepted by Asterisk.
Can someone instruct me how the syntax should look like?
Here is what it looks like today (the actual url has been masked):
IN NAPTR 100 10 “u” “sip+E2U” “!^.*$!sip:firstname.lastname@example.org!i” .
BTW: I get regex delimiter error in Asterisk.
