L2TP Client: SNOM
Jump to navigation Jump to search
NOT RECOMMENDED AT THIS TIME
- Some SNOM phones support adding an L2TP firmware patch that gives the phone the ability to connect to a L2TP server.
- This can help bypass firewalls and NAT/CGNAT which can cause problems with VoIP.
- The config files need to be put in a .tar file hosted on a webserver for the SNOM to fetch.
- Further details are on the SNOM website: https://service.snom.com/display/wiki/Install+and+configure+L2TP+on+Snom+Deskphones
Example config files:
Below is config to connect to our L2TP service.
- Be aware though that this will mean the SNOM is on a public IP address and open to the internet and not behind a firewall. We do not recommend using our normal L2TP service on a SNOM due to the risks involved in having a SNOM on the internet in this way.
- If you decide to use this as an option, be sure to have very secure http/admin username/passwords on your phone.
- At some point A&A may offer a service that allows the SNOM to connect to a protected, private, network which only has access to the VoIP servers.
