Bring the Power of VoIP to Your Phone System


SIP stands for Session Initiation Protocol. SIP Trunk Lines represent the number of simultaneous calls to the public telephone network that can be made at the same time. SIP Trunk Lines are the virtual equivalent of lines coming in from the phone company or channels on a T1 circuit.


Voxox delivers powerful functionality to your new or existing phone system, helping to reduce your phone and internet costs with competitive rates and one plan for voice and data. If you already have a substantial investment in PBX or key system equipment, with Voxox you can take advantage of VoIP features and cost savings.

Because lines can easily be added or removed as your business needs fluctuate, SIP Trunks enable your business to create a more scalable solution for the growth of your network.
