Summary:                    [patch] 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

We do have rport support in 1.4, so it's strange that it doesn't work. If
you have nat=never it is turned off. 

That needs to be fixed. 

Bretts patch was for svn trunk, obviously he missed that you reported
against 1.4. 

Klaus, you know that we also need a trace from your Asterisk when you file
bug reports against SIP. This time, I would like to see "sip show settings"
and a transaction with verbosity and debug output. THanks.

The symmetric reply to all requests is handled in another bug report. I'll
add a reference too it soon.
