I would be quite interested to learn how you got the password out of the Fritz...
That sounds like it could save me a hell of a lot of time.
Download the Fritzbox config file and use this tool in conjunction with the password you used to encrypt the fritz config file
Please note - you are uploading your configuration file to a 3rd party site which theoretically could expose your passwords if you use the link above. They offer an offline version here - http://www.mengelke.de/Projekte/FritzBoxJSTool.html so I recommend you download that locally and run it without an internet connection and/or in a sandboxed/restricted environment so you have confidence your decrypted information is not intercepted/transmitted.
Much appreciated. Thank you.
I have to say I find the treatment of those wanting to use their own SIP hardware (whether it be by providers or members of this forum) a little harsh.
I've always used a mid-range Cisco ISR i.e. 2800 (now 2900) series. These routers have perfectly good FXS capabilities themselves - being forced to have the Fritz knocking around in the bottom of my rack is sub-optimum to say the least, not to mention the extra cabling and power supply that go with it.
But worse than having another billing arrangement with another company for SIP? It's good that we don't have to make that choice anymore.
