>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Resources/res_pjsip

>         Environment: Debian Sid
>            Reporter: erebus

> In source file asterisk/res/res_pjsip/location.c, there are several lines which pass AOR identifiers into regular expressions without proper escaping.
> For AORs that include regex metacharacters (such as +0000, bobby+tables or Tables*Bobby), this means that the resulting regex will be incorrect, breaking contact lookups and inbound calling.
> I suggest that AOR identifiers be escaped before being inserted into regular expressions.
