Description:Some people think they NAPTR-records like this one:
8.0.4.2.4.1.1.4.2.2.9.4.e164.arpa       NAPTR   100 100 "u" "E2U+h323:voice" "!^\\+492241142(.*)$!h323:2\\1@pbx-bi.corponet.info!i" .
(the 'i' means: case insensitive match ...)

The patch makes asterisk ignore the i (or any other of the /very usefull/ things) and parse the record correctly.

This patch doesn't make much sense because it breaks how things SHOULD work.  If people can't form valid enum NAPTR records they need to read.  We can't go changing how asterisk processes them because then we also have to change how the world processes them too.

This doesn't break anything and NAPTR-records with 'i' or wathever at the end are still valid (see RFC 3403 6.1). NAPTR-records without the extra-letter are still parsed correctly.

RFC 3403:
---------
6. Examples
6.1 URN Example
[...]
cid.urn.arpa.
 ;;       order pref flags service        regexp           replacement
 IN NAPTR 100   10   ""    ""  "!^urn:cid:.+@([^\.]+\.)(.*)$!\2!i"    .
---------

I know that this is not a ENUM NAPTR-record and it doesn't make sense with ENUM but it really is valid and is used.

Examples:
1.0.2.4.1.3.3.6.1.1.7.9.4.e164.arpa     NAPTR   100 100 "u" "E2U+h323" "!^\\+4971163314(.*)$!h323:\\1@foxi.vc.dfn.de!i" .

8.0.4.1.4.1.1.4.2.2.9.4.e164.arpa       NAPTR   100 100 "u" "E2U+h323:voice" "!^\\+492241141(.*)$!h323:1\\1@pbx-bi.corponet.info!i" .

This patch doesn't work.  I added a few records with an i and it wouldn't work.
