[asterisk-users] can't hear anything at incoming calls

[Michael Herrmann]

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?
