Summary:                    ? in register= string breaks registration
Description: 
If you put '?' (w/o quotation) in register= string in sip.conf, asterisk
does not parse it properly.

One of my register= string has '?' in its password section, and asterisk
can't parse it properly. This does not affect other lines in sip.conf

The string I used is as bellow,

register =>xxx at xxx.com:abc!5j5?!9!:xxx at hostip/123

Does '?' have been used as some token? Maybe I did not get that. I am
pretty sure I haven't seen it in change.log or sip.conf.sample.

The registration strings have worked fine with version 1.4.2, 1.6.0, and
1.6.1.0.

---------------------------------------------------------------------- 
The patch on 15008 will fix this for you, although by changing the format
slightly.  That patch will allow you to quote nearly any field (exception
of transport and portnum, which don't allow arbitrary characters, anyway)
to prevent characters within from being interpreted as delimiters.
