Threshold supports TDM PRI voice circuits.  However, most enterprises have moved to SIP trunks and not all SIP trunks are alike…

  • Threshold has a geo-redundant voice network that protects clients from single points of failure.
  • DIDs are available in most of the US/Canada including Hawaii and Alaska.
  • Our flat rate SIP trunk includes all local usage.
  • Customers can connect via public internet, private transport or via most major carrier hotel marketplaces.
  • Burst trunk capability above your commitment level.  So when you have occasional peak usage, you can process the calls.
  • Fast and easy setup of your services
  • Toll-free carrier redundancy. Threshold will put your Toll-free number on multiple carriers to reduce the impact of any carrier issues.
