Summary:                    chan_sip ignores rport and does not reply to source
IP:port
Description: 
Hi!

I have defined a peer in sip.conf:
[klaus]
type=peer
username=klaus
secret=password
host=dynamic
context=fromklaus

Then I register with eyebeam. Eyebeam sets the "rport" parameter in via
header which should activate symmetric signaling. Further, even if rport is
missing, the RFC 3261 mandates that replies should be sent to the source IP
of the request, not the IP in the Via header (the latter one should only be
used if the first one fails (e.g. ICMP error)).

Bug: Asterisk sends the request back to the IP in the Via header. I know I
can change behavior by setting nat=yes, but even without this setting
Asterisk should be standard conform.

I used Asterisk 1.4.21.1
