Hello, my last question (see copy at the bottom of this mail) got no answer - and as I allways got one, I suppose that something has gone wrong.
Or may be I put an question that is not within the scope of this list? I would appreciate if somebody could indicate this to me. My phones are ready, but I cannot use them - and I suppose it has to do with firewall problems. Thank you!

In the OpenSIPS-Server, I opened the incoming port UDP 5060 in IPTABLES for incoming calls (in the moment still restricted to the dyndns of my home-IP = $IPTABLES -A INPUT -p udp -s xxx.xxx.xxx.xxx --dport 5060 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT) and permited the outgoing port UDP 5060 in IPTABLES for outgoing calls to any IP (= IPTABLES -A OUTPUT -p udp --dport 5060 -m state --state NEW -j ACCEPT). In my Home-Router, I opened the port UDP 5060 in IPTABLES for incoming calls for the two VoIP-Phones (i.e. their respective IP). And the outgoing requests are permited anyway. But I can not make/receive any call - I try to call from one VoIP-Phone to another (the traffic must leave my Home Network, enter the dedicated OpenSIP-Server, leave it and enter my Home Network). The calling VoIP-Phone is waiting some seconds and then indicating in it's display the message "Network failure". Is there something wrong in my concept? Or can you give me any hints why the connections might fail? Thank you very much! Regards, Markus
