GTI provides a prepaid service for small companies or call shops that regularly make international calls. Your company or call shop can be anywhere in the world. As long as you have dedicated Internet access (non dial-up) our service fits your needs.

Here's how you get started:

1. Be sure you have the following setup at your facility:

a. Internet:
Approx 30kbps Internet connection per concurrent call expected. This can be dedicated internet, or a service where voice can be prioritised over regular data traffic. Low jitter and latency will maximise the call quality.

b. Network:
The service can be run from either static or dynamic IP addressing - preferably using a public IP, although NAT connections can be supported in some cases. Any installed firewall must be disabled to allow incoming and outgoing voice traffic.

c. Hardware:
Analogue Telephone Adapter (ATA), IP connected Softswitch/PBX, or other compatable internet telephony device. Device must support SIP and g729 codec.

2. Send the following information to support@globaltelecomint.com :

a. Contact Details - email address of technical contact
b. Details of your internet connection so we may asess if it is suitable for our service
c. Details of your office configuration: Phone to ATA, PBX to ATA, etc.
d. Number of individual lines you want to configure, i.e. How many ATA's do you want connected? (e.g. a PBX line out to a single ATA is one individual line for multiple users)

3. Upon confimation that your network meets the requirements you will be notified by us to proceed to step #4.

4. Prepay for your service

5. You will receive an email notification within 24 hours that your service is activated. From this information you can go online (www.gtiprepaid.com) to check your usage, topup your account and manage your calling patterns all online, view the terms and conditions of service.
