Tried opening he example RTP ports, no success...I tried using
another router and PC only by capturing with wireshark it seems that
RTP traffic is using port 5062...But in my setup port 5062 is open
and still no success...

I am using a NanoStation 2 in Router mode.The NS is

The past few days I'm trying to use a VoIP client software
to connect
to my VoIP account.I use Ekiga Softphone to do so, which
requires UDP
ports 3478-3479 and 5000-5100 to be open.
So I have opened these ports both on my neighbor's router
and on the
NS.The problem that I'm encountering is that although I
manage to
register to the VoIP service, when I answer an incoming call
the caller
is able to hear me, but I'm not able to hear the caller.So I
used
wireshark and figured that there is no incoming traffic on
my end.
I have used many linux VoIP clients with PCs connecting
straight
forward to an ADSL router and worked perfectly.So this has
something to
do with NS...
You also need incoming RTP ports open.
| SIP |
5000 to 5100 |
UDP |
SIP signalling, listen port: 5060 |
| STUN |
3478 to 3479 |
UDP |
Outgoing traffic to the STUN server |
| RTP |
Random/Various |
UDP |
Incoming traffic from the other end. Often 5004, 7070,
16382 |
Somehow the incoming RTP ports happen automagically in most case,
I'd
like to understand how.
Treating it as magic for the moment, I've noticed that turning on
ip_nat_sip on linux iptables has the effect of
blocking *outgoing* audio. Ekiga seems to work best with no fancy
help
from the router. Is there some kind of
"stateful SIP" option that can be turned off?
