Not possible to establish a connection at all... I *suppose* Deutsche Telekom just allow a logon on their servers from the IP of the user, who tries to log on (with other words: my VoIP login can just log on from my current IP)... This would explain why I didn't got my mobile phone connecting to the Telekom's server and establish a call... I also tried to stop Asterisk and all other network services on my Linux-Box Firewall/Gateway, including the traffic shaper (in the case, this was the problem), then connect my Thomson phone to the Telekom's server and call my father in law. Always the same problem... So, tomorrow I'll get another VoIP phone from a colleque (Elmeg IP 290). I'll connect it to my network and my Asterisk and will try to call my father in law for a test. I really do *not* expect any change in the situation... I think, the problem should be somewhere by Deutsche Telekom... What is your opinion? Btw: I did all tests with my father in law, since he had time for me today, but the problem exists an almost all calls, incoming or outgoing, no matter from/to which network provider...

There is a special "DeutschlandLAN SIP-Trunk Pure" where it does not depend on your DSL account (as it is standard with most other VoIP providers).> This would explain why I didn't got my mobile phone connecting to the > Telekom's server and establish a call... > > I also tried to stop Asterisk and all other network services on my > Linux-Box Firewall/Gateway, including the traffic shaper (in the case, > this was the problem), then connect my Thomson phone to the Telekom's > server and call my father in law. > Always the same problem... > > So, tomorrow I'll get another VoIP phone from a colleque (Elmeg IP 290). > I'll connect it to my network and my Asterisk and will try to call my > father in law for a test. > > I really do *not* expect any change in the situation...

You mean that the Thomson phone is registering to Deutsche Telekom? I thought it was registering to your Asterisk server. Maybe it would be a good idea to tell *exactly* what your network setup is, because I'd certainly assumed something that's clearly not true; maybe others here have as well. Basically, what SIP phones (hardware or software) are you using, what are they registering to, and what role is Asterisk playing in all of this? How do calls to/from the public phone network get routed from/to your telephones?

Normally my Thomson phone is registering to my Asterisk server. I tried to register the Thomson phone directly to Telekom's server, to check if the problem could be in my Asterisk...> Maybe it would be a good idea to tell *exactly* what your network setup is, > because I'd certainly assumed something that's clearly not true; maybe others > here have as well.Well, I'll try: - DSL-Modem, connected to a BananaPI with Debian 9 - On the BananaPI, PPPoE to connect to the Internet, iptables and some scripts to manage the Gateway and Firewall - Many VLANs, some of them can use the Internet via NAT - The phones are in an own VLAN without any routing to the Internet (exception for my phone was temporarily made to allow the tests) - In the phone's VLAN there is the Asterisk server, running on the same BananaPI the act as Gateway/Firewall - Mobile phone connected via WLAN in the same VLAN used from the PCs, and with routing to the Internet via NAT> Basically, what SIP phones (hardware or software) are you using, what are they > registering to, and what role is Asterisk playing in all of this? How do > calls to/from the public phone network get routed from/to your telephones?We have two phones Thomson ST2022, registering to the Asterisk server. The Asterisk server registers to Deutsche Telekom and MessageNet. All calls are normally routed by Asterisk to Deutsche Telekom. Some *incoming* calls to an italian number arrives via MessageNet and will be directed to my Thomson phone. What I tried connecting the phone directly to the Internet and the servers of Deutsche Telekom was just a test, not the normal situation. Do I have explained my current situation? Of course I can send extract of configurations, if needed... What I'll do tomorrow with a test phone is: 1) connecting it to my Asterisk and try to make a call 2) connecting it directly to the servers of Deutsche Telekom (using my network) and try to make a call Thanks a lot for your help Luca Bertoncello (lucabert at lucabert.de)
