Advantages of Voice Services
You can outsource all your telecommunications services to ST, including all telephony functionality.
ST's Voice Services provide a total package of telephony services and support. You can call other companies connected via ST's main exchange without paying call charges. You may connect several branches of your organisation into a single telephony network, including staff working from home.

ST offers you the choice of the following Voice Services.

- Standard Telephony Services (TS)
This is a traditionally hosted telephony service that offers the following advantages:

- Extensive functionality
- ST has its own telephone exchange  
- Monthly subscription costs (one-off connection charges)
- Fast delivery anywhere at Schiphol
- Interesting in combination with GSMs, due to coupling with mobile network
- Can be supplied from 1 to x-number of connections

- Telephony Services in combination with GSM
The ST-GSM service ensures that your GSMs have the same functionality as our advanced telephone exchange. Your mobile phones can also be reached via the internal telephone number. The use of GSMs is therefore more efficient and manageable. Accessibility and user-friendliness are improved, while lower rates result in a very attractive financial advantage.
