Portable IP Telephone

Question:

I hope you can help, last month I bought a Snom370 telephone through yourselves, and wondered if you have a SIP enabled portable telephone as an available option ? We have a team who walk between buildings covering up to 100 sq.meters. We have already tried the Snom M3, but this does not have a far enough reach from the base station.

You could try a Snom M3 Repeater. This will extend the range. If you can arrange the base station in the middle, and repeaters around in a circle then you can cover a huge area. Calls hand over between repeaters as you walk.

Other option is something like a Gigaset S685. The handsets have a `best base` feature where you can register a handset to more than one base station. You need to be a little bit clever with setting up SIP accounts. Each handset needs a SIP account for each base. These then have to be setup to all ring together. This solution does not allow handover while calls are in progress.

A long term option would be the Snom M9 phone. A roaming feature is in the roadmap for this phone, but probably at least 1 year away from launch.

Snom Repeaters with Gigaset Dect Phones

To fix problems using Snom Dect repeaters and Gigaset phones. (well, there is no problem, but some people seem to have problems)

We have today tested in detail the Snom repeater with every kind of Gigaset base with all the common firmware versions.

It has performed flawlessly. Exactly as expected.

Tips:

1) It is easier if you switch the phone to prefer PSTN lines rather than VoIP. Then reverse this setting afterwards. Setting is in Menu, Settings, Telephony, Default Line. Set to Fixed Line while doing the registration. It does work without changing this setting but will display a VoIP error.

2) You need to enable Repeater mode on the base station beforehand. Menu, Settings, Base, Add. Features, Repeater Mode. You may need to disabled eco mode before repeater mode can be enabled.

3) You need to follow the manual registration method described in the instruction leaflet included with the repeater. Automatic registration appears to be only for Snom DECT bases.
