SIP Trunking FAQs

SIP trunking is a way to connect an on-premise IP phone system or a legacy phone system via VoIP gateway to a VoIP service provider.

  • Least expensive route to deploy VoIP services throughout an organization
  • Does not require new PBX or phone hardware
  • Allows for quick addition and removal of voice channels – easily scales
  • Predictable monthly costs
  • Support of modern VoIP features such as SMS is only possible with the modern IP PBX
  • Offers finite number of concurrent channels beyond which end users receive busy signals
  • Requires in-house maintenance expertise of on-premise PBX system

You will need one channel for each concurrent phone call. It is best to base this number on peak times when most of your users are on the phone. For example, if during peak time hours your business uses 10 lines, you require 10 channels. 

T.38 faxing protocol is guaranteed for all outbound calls with the 2-Way SIP Trunk with T.38 pricing plan.
