How does MEX work?

When a MEX user calls from their mobile, the call is routed through the phone system before connecting to the recipient. This way mobile users get access to the same features and services the phone system offers.

Why choose MEX?

  • Integrated services, mobile users get the same features as on a landline or computer.
  • More functionality, besides traditional MEX there is an IP based variant that uses internet telephony.

MEX in the Nordics

MEX technology is mainly found in the Nordic region, especially in Sweden and Finland, linked to unique market needs and technology trends. If you have MEX enabled, all functionality is handled by your phone system provider, such as voicemail and call forwarding, so all settings are in one place.
