Summary:                    [patch] Wrong country code identifier "%2B" instead
of "+" in Remote-Party-ID
Description: 
Starting with version 1.8.x Asterisk is delivering a wrong prefix "%2B"
instead of "+" in Remote-Part-ID as shown in the folowing trace snapshot
(some fields replaced by xxxxxxxxxxx for privacy reasons):

From: "xxxxxxxxxxxx" <sip:+498421931296 at 141.78.x.x>;tag=as1cb29c87

The call is rejected by Deutsche Telekom host with the error message
"Got SIP response 500 "Internal Server Error" back from
193.174.1.234:5060"

This phenomenon first observed with Asterisk 1.8.1 was reproducable also
with Asterisk 1.8.2.2.

This is my first Asterisk bug report; please apologize any deficiencies.

I have the same issue with Verizon SIP Interconnect.

When the RPID is URI encoded ("%2B" instead of "+"), they reject the call
with "SIP/2.0 403 Calling Party Information Not Found".

Maybe they are doing it wrong, but it would be great to add an option to
maintain compatibility.
