Configuration of an elmeg IP290 VoIP Telephone with internet access via a Bintec X2302 Router for authentication at the VoIP Provider Sipgate
This FAQ describes the configuration of the elmeg IP290 / Snom 190 VoIP phones for the login to the VoIP Provider Sipgate. A Bintec Router (e.g. Bintec X2302) provides the internet access in this case.


Conditions:
  • The registration at the VoIP Provider (e.g. Sipgate) is required
  • Internet access of the Bintec router is already configured. Several instructions regarding the configuration of an internet access can be found in the category Internet Access/xDSL
  • A DHCP server should be available within the LAN from which the VoIP phone receives an IP address and the standard gateway. It is also possible that the Bintec router acts as the DHCP server.
  • At the elmeg IP290 / Snom 190 VoIP phone software revision 3.60i has to be installed at least.

Configuration of the elmeg IP290 / Snom 190 VoIP phone:
During the start up of the IP phone an IP address will be assigned from the DHCP server. Via this address (is shown in the display during the boot sequence) it is possible to access the web interface of the phone via http.

In menu item "Line 1" the settings of the VoIP account are stored. At the flag "login" the user account and login data of Sipgate have to be entered.



At the flag "NAT" the STUN Server of the VoIP-Providers have to be entered. An interval of 10 seconds causes a permanent connection between the IP-phone and the SIP Provider. Because of this setting no further NAT entries (e.g. port forwarding etc.) are necessary at the Bintec router. 

Caution: Due to the permanent connection between the IP-phone and the SIP Provider the internet connection will not be disconnected and unmeant costs could be generated.


After successful login of the IP-phone at the VoIP Provider the own phone number is shown in the display.

Debug messages of the router during the dial-up to the VoIP Provider:
