Pay as you go SIP calls


Aatrox Communications’ Pay-As-You-Go SIP Trunk plan allows you to connect an IP or analog PBX system to the telephone network, drastically reduce call costs, and use your existing phone numbers from anywhere in the world. 

If you find that your business is predominantly calling landlines, a PAYG plan is probably the right one for you.

With no contract and no setup fee, this is the perfect way to start saving money on your business phone system with VoIP.
