Technical Hints

Factory reset of DECT Siemens Gigaset A580IP, C475IP, S685IP

Resetting the base station using a key on the base station

All individual settings are reset. Warning, your phone will not function after this process and will need to be setup again.

The system PIN will also be reset to “0000” and all additional handsets de-registered

Steps:

  • Remove the cable connections from the base station, both network and phone.
  • Remove the base station mains adapter from the socket
  • Press and hold the blue registration/paging button.
  • Plug the mains adapter back into the power socket.
  • Keep hold the blue registration/paging key (at least 10 sec.).
  • Release the registration/paging key. The base station has now been reset.

    You then need to start again with your device as if just delivered. You need need to enter all SIP details and register handsets.

Snom – Bootloader Versions

Did you know there are two parts to Snom version 7 firmware?

1. Main application (with a version code like 7.3.14)

2. The bootloader (with a version code like 1.1.3-s)

Most Snom users keep their application up-to-date but the bootloader is often neglected.

How to Check:

  • Web browse to your Snom phone

  • Click onto `System Information`

  • View your bootloader version

Our Findings:

  • 1.1.3-s is OK

  • 1.1.3-m or older needs an upgrade

If no bootloader version is shown, your bootloader is archaic! It would be best to upgrade.

Old Bootloader Symptoms:

  • Headsets not properly detected

  • Extension keyboards not properly detected

  • Phones may not boot up when headsets or extension keyboards are connected

  • Snom300’s may show strange characters on screen during bootup

How to upgrade:

If your Snom phones are managed by ProVu, then we can carry out these changes through our provisioning server – please just ask us!

Otherwise, you need to load a firmware image containing a bootloader.

Snom – Firmware Update (Snom300, Snom320, Snom360, Snom370)

Current recommended Snom firmware versions are:

6.5.20 (with linux 3.38 and jffs2 file system)
7.3.14 (with 1.1.3-s bootloader or higher)
7.3.29 (with 1.1.3-s bootloader or higher)

We do not suggest V8 for Snom3xx series phones unless you need OCS support or you are feeling brave.

7.3.29 seems to fix a few minor issues with long term stability. This is for users who take hundreds of calls per day and who use the DND feature. Has fixed a lot of people’s issues.

If you use Action URLs then please use 7.3.14 or 7.3.29. Otherwise you may have issues with call transfers.

Above my opinion based on supporting Snom phones in the UK.

Siemens Gigaset – Copy Address Book to Each Handset

The address book on a Siemens Gigaset DECT Phone can be copied over via the handset to another slave phone registered with the base station, without having to browse to the web interface.

  • Go to the address book on your handset.

  • Select options on the soft key.

  • From the options menu select copy list.

  • From the generated list select which handset you wish to copy your address book to.

Remember all Siemens Gigaset DECT phones are compatible with one and other. Up to six of any combination of A58, C47 or S68 handsets can be registered with any one base.

Snom – See What’s Happening on the Screen of a Remote Phone

<%ThickBox(http://ron.provu.co.uk/~paul/pauls_screen.png|Snom360 Screenshot)%>

This is a good one for checking the common issue where a customer has turned on Do-Not-Disturb without realising it or just seeing what’s on the screen in general.

I have also used it to demonstrate the phone in training sessions.

You can view the bitmap currently shown on the phone’s screen in a web browser by going to:

http://ip.addr.of.phone/screen.bmp

This works on all Snom phones (including the 800 series!) with version 7 firmware and up. It’s a static image but you can keep hitting refresh in your browser to update the image.

Siemens Gigaset – Automatic PSTN Failover

All Siemens Gigaset VoIP DECT handsets support 2 VoIP and 1 PSTN / Landline call simultaneously.

Now all of the base stations within the range, have the ability to perform automatic failover to your landline. Quite simply, if for any reason your VoIP service or PBX fails causing your internet connection to go down, the Siemens Gigaset will automatically send calls over the landline connection plugged into the base station instead. No chance of missing an important call.

Just configure your base station to fail over to PSTN on the web interface.
