VoIP hardware is developing fast - this is where you ask all those “how do I make my SIP Telephone, Adapter or Asterisk box work with my voip provider?” questions.

Have you tried a factory reset? TFTP upgrade?

If these fail according to the manual below in these situations the only option then is a return to the Snom for repair (see pages 52 onwards):

Factory reset
It appears with this phone that you can only do a factory reset from the web interface (but still give that a try first). Refer to the manual above, but in brief: http://[IPAddress]/advanced.htm?reset=Reset
Note: Depending on where it is failing it is possible the admin web page could be running but other services are not - so still check/try the above.

If that fails then try a TFTP recovery (see below).

TFTP recovery method
Refer to this page:
http://wiki.snom.com/Firmware/Update/TFTP_Update

Related pages:
http://wiki.snom.com/Firmware
The manual mentions http://snom.com/firmware.html = NO longer valid, so see: http://www.snom.com/en/support/download/firmware/

Another less technical manual:

Hope this helps.

There must be a factory reset on the handset? Maybe holding down some keys while it boots up?
If a built in factory hardware reset exists then invoking it will likely be something like this:
Turn off phone, holding down keys like * or # for 30 seconds, turn on phone whilst still holding down those keys.

NOTE: This isn't the factory reset for the phone but I would imagine if one exists it will be something like that.[/b]

Be aware though this type of reset often requires a fully working firmware.... and devices which retain a backup of the previous firmware. Indeed firmware updates are a great way of breaking devices preventing them from then receiving further updates or having configurations reset.

Fortunately internal firmware reset methods do often tend to exist, e.g: via JTAG flashing which is usually how the firmware is originally installed: http://en.wikipedia.org/wiki/Joint_Test_Action_Group

JTAG is *very* complex and involves taking the phone apart etc. This will likely be how be how snom will repair the phone - personally I would advise you to just pay them to do it. (or buy a replacement phone)

Ok very good news - this means you should be able to recover it yourself.

TFTP = Trivial File Transfer Protocol
http://en.wikipedia.org/wiki/Trivial_Fi ... r_Protocol

In simple English, TFTP works by storing the firmware on another computer on the same network and then running a TFTP server on that computer. When the TFTP is ready you then tell the device to retrieve (download) the firmware from the TFTP server.

This is what the device is asking for... the network details of the TFTP server.

I will point you in the direction of a TFTP server: http://www.solarwinds.com/products/free ... erver.aspx

Note: I am guessing your using Windows. Linux is very well catered for.
