Summary:                    [patch] Realtime is broken, blank strings aren't
valid any more
Description: 
For a few years i've used a blank strings for values that i didn't wish to
specify. Recent commit into asterisk-addons 1.6.0 (revision 1070) broke
everything. A lot of problems arise, since my blank values aren't blank
anymore. For example, former blank fields 'fromuser' and 'fromdomain'
become not blank with this patch, and i get an error: SIP/2.0 400 Bad
Request – ‘Malformed/Missing FROM: field’.
Because my From header looks like this: From: "1000" <sip: @
>tag=as3e28b5d2

This problem doesn't have a simple solution, if you wish to support two
different blank values (empty strings and NULL) you should implement that
in the asterisk first. Replacing either value with non-empty strings is a
very bad idea, because there will be a lot of problems in both cases.

For now i wish that change would be reverted. Thank you in advance!

  Further reduce the encoded blank values back to blank in the realtime
API.
