With the snom ONE calls can be made into the public telephone
network (PSTN) either by standard PSTN gateways or by SIP trunking
providers. The snom ONE supports a range of other products, such as fax,
as long as they support the SIP protocol.
snom ONE also increases the productivity of each user by supporting CSTA, which allows an easy integration into existing CRM systems. It also supports multiple languages and multiple time zones, which can be set up on system and user level.
