Save costs with VSAT Telephony

VSAT Telephony by Castor Marine offers business voice call quality at low costs per call. When a call is set-up, we allocate dedicated bandwidth, optimized for our Telephone services, ensuring high quality clear calls. As a Satellite Network Operator we offer the best of both worlds.

Outbound calling

The service for VSAT Telephony by Castor Marine allows outbound calls at competitive rates to both fixed and mobile destinations worldwide. Our customers save significantly on costs for voice calling compared to an Inmarsat or Iridium service. 

Inbound calling

For inbound calling we use a local number. By doing so we allow users to make calls from a yacht to a number ashore at the equivalent cost of a local call. We provide you with a standard Dutch local phone number, but you can also select local numbers from more than 55 countries worldwide.

Benefits of VSAT Telephony

  • Business voice call quality phone calls

  • Outbound and inbound options

  • Competitive or local rates

  • Works on top of your VSAT Internet connection
