Summary: [patch] Temporary answers are sent to the wrong IP
Description:
When sending a bad message to asterisk we use a temporary pvt to respond.
If I send a message from a SIP device behind a NAT to an Asterisk on a
public IP, Asterisk ALWAYS answer to the address in the via: header. This
is not compliant with RFC 3261 and also opens up for using Asterisk for
sending messages to other host. If I send a SIP message with a via: header
for pbx.digium.com all the responses will be sent there.
We should really ALWAYS send responses to the sender's IP and port
(another issue here in the tracker correctly points that out). In other
cases, you can sort it out by setting NAT=yes in the general section.
However, that doesn't apply on temp_pvt.
