Summary:                    Caller Name does not preserve multiple spaces
Description: 
When asterisk receives an INVITE with a Caller Name containing multiple
spaces, only one space is preserved.

Other SIP user agents / proxies / gateways as well as previous releases of
asterisk do preserve multiple spaces.

For example, "Victoria     BC" <2505551234> becomes "Victoria BC"
<2505551234> which is undesired.

I believe this only comes in to play if you have string with a run of
sequences like this:

Header-Name: Some (comment
 that goes here) Value

becomes "Some Value" with a single space, not "Some  Value" with two
spaces because of the comment.

Furthermore, we are dealing with a quoted-string that contains the Caller
Name.  My understanding is that the only case spaces will be removed are
the spaces immediately following a CRLF, for example:

Caller-Name: "Bob's
   Pizza"

would become

Caller-Name: "Bob's Pizza"
