asterisk users - Nov 2009 - can't hear anything at incoming calls

Hi out there,

I think i've everything set up properly, outbound calls are working fine,
but
at incoming calls I can't hear anything, but the other one is able to hear
me
perfectly.

I'm using an asterisk 1.6.1.10 in my internal network in a NAT, connected to
my sip-provider using a trunk.
Firewall settings on the router are:
forward UDP port 5060,5004,10000-20000 to asterisk server
Firewall on asterisk server is switched off (for better testing)

[sip.conf]
[general]
port=5060
bindaddr=0.0.0.0
language = de
externhost=intakt-musik.dyndns.org
externip=intakt-musik.dyndns.org
localnet=192.168.0.0/255.255.255.0
nat=yes
register => USER:PASS at sipconnect.sipgate.de/USER

[sipconnect.sipgate.de]
type = friend
host = sipconnect.sipgate.de
outboundproxy = sipconnect.live.sipgate.de
port = 5060
username = USER
fromuser = USER
fromdomain = sipconnect.sipgate.de
secret = PASS
dtmfmode = rfc2833
insecure = port,invite
;insecure = very
canreinvite = no
registertimeout = 600
disallow = all
allow = alaw
allow = ulaw
context = sipconnect.sipgate.de


Auntie google is not very helpful for me.
They all say, it looks like a firewall problem on the router.
But I'm sure this is set up correctly.

Any ideas?

If all signs point to mis-configuration of your firewall, why not prove them
wrong (while in the process getting more details).... just add wireshark to
the mix.  You can then watch the traffic and be able to quickly identify if
any is being lost due to blocked ingress/egress ports.

Shouldn't you have 'nat=yes' in your peer context
[sipconnect.sipgate.de]
and not in [general]?
