More than 10,000 Gradwell lines are used by SME customers with their own onsite PBXes. Calls are connected either to SIP-based phone systems (for example, 3cx on Windows) or Asterisk using the IAX protocol.

To support these users, Gradwell is pleased to announce its Inclusive Calls UK and International SIP/IAX Trunk products.

These products:
• are designed for businesses with up to 5 people, making up to 4,000 minutes of inclusive calls per month
• gives a small business a known, fixed monthly fee for its calls
• are suitable for any customer with its own onsite Asterisk server or SIP- based PBX.

There are two new tariff options available:

1. UK Unlimited Trunk tariff – offering unlimited UK calls to 01, 02 and 03 numbers (subject to a fair use check at 4,000 minutes)
2. International Unlimited Trunk tariff – offering Unlimited International Calls to landlines (same fair use check applies) in the main 35 Western countries.

Existing customers may re-grade, free of charge. A full list of countries is available on Gradwell’s website: http://www.gradwell.com/voip/
