I have been using snom for 20 years and am quite happy with respect to durability, call quality, and ease of configuration. These snom phones will replace some older ISDN phones on the Auerswald telephone system at home. I can absolutely recommend snom.

EN DEUXIEME LIGNE VOLP.. AU DEBUT DEUX VOYANT CLIGNOTAIT PUIS PLUS RIEN ECRAN ETEIND
IMPOSSIBILITE DE LE CONFIGURER Y A T IL UN BOUTON DE MARCHE ARRET ???

Brilliant bit of kit – wish I’d bought one years ago – use it with my CircleLoop account and works better than my landline !

Easy to configure.
Sound quality is good.
Plastic feeling when pushing the buttons.

This phone was easy to provision with our 3CX phone system. It is a basic phone however for our use it works just fine.
