Snom M400 Single-Cell DECT Base Station

The Snom M400 is a DECT base station with the full range of business telephony features, designed to start as a single-cell system and grow into a dual-cell installation when coverage or capacity needs to increase. In a dual-cell setup it delivers uninterrupted availability with seamless handover, a powerful DECT call manager for up to 20 parallel calls and support for up to 40 SIP accounts.

Its natural handset partner is the Snom M30 — one M400 supports up to twenty M30 handsets with ten parallel SIP calls, ideal for offices, retail floors and practices where staff roam. The M400 can also be used with all Snom multicell endpoints, and the automated dual-cell chain to the local network makes upscaling straightforward.

If your site needs more than two cells — large warehouses, hotels or multi-floor buildings — step up to the Snom M900 multicell base station instead.

Frequently asked questions

How many handsets and calls does the M400 support?

With M30 handsets, one M400 supports up to twenty handsets handling ten parallel SIP calls. In a dual-cell installation the DECT call manager scales to 20 parallel calls with up to 40 SIP accounts.

What does dual-cell mean in practice?

Two M400 bases form a chained installation: coverage extends across a larger area, availability is uninterrupted and calls hand over seamlessly between the two cells as users move around.

Which handsets should I pair with it?

The Snom M30 is the natural partner and the M400 can be used with all Snom multicell endpoints. Tell us your headcount and floor plan and we will recommend the right mix.

When should I choose the M900 instead?

If you need more than two cells — for example seamless roaming across a whole building or campus — the multicell M900 with its integrated DECT manager is the better platform.
