SIP Trunking


The emerging standard in enterprise voice.

One connection to thousands of calls, at a fraction of the costs.


SIP Trunking
  SIP (Session Initiation Protocol) is the key to unlocking the powerful potential of next-generation IP-based communications. By linking PBXs in multiple locations with each other and the PSTN, this innovative solution allows large organizations to replace costly ISDN PRIs and traditional lines to reduce costs and handle any call volume.

Aggregate your channels


ThinkTel specializes in delivering network-neutral SIP Trunking solutions that will streamline your voice infrastructure and allow you to manage your capacity more efficiently.

  • Seamlessly pool and dynamically allocate your channel capacity across multiple sites
  • Create an extended local calling area by assigning DIDs from multiple rate centres to a single SIP trunk
  • Eliminate the need to pay for telephone services at each location

Pay only for what you need


Most businesses that rely on traditional voice solutions pay for up to 50% more lines than they need - just to be safe. ThinkTel's innovations in service delivery can help reduce your monthly telecom expenses from 20 to 50%.

  • Subscribe only to the minimum number of fixed channels needed at all times
  • Rely on Capacity on Demand's burst channels to handle peaks in call volumes
  • Have sufficient capacity to ensure conference calls do not impact your ability to place or receive calls

100% Business Continuity


These reductions in cost don't come at the price of reliability, either. We have been delivering SIP-based voice services since their inception and have become the IP voice provider of Fortune 100s, government agencies and public institutions.

  • Bank on our highly-redundant national voice network built on carrier-class technology
  • Support multiple network paths over diverse carriers and up to 8 simultaneous IP gateways
  • Enable any one site to act as a complete fail-over to ensure business continuity
  • Rely on Surecall to specify a call forwarding number for each active DID should a SIP trunk go down


Is SIP Trunking right for your business?



  • Do you have an IP-ready PBX, or are you thinking about purchasing a new PBX?
  • Do you need multiple PRIs to ensure sufficient capacity?
  • Do you have multiple office sites?
  • Do you experience highly variable call volume, experience busy signals or insufficient lines?

If you answered YES to any of these questions, SIP Trunking is the right solution for your business!

Important note regarding 911 service: VoIP 911 service has certain limitations relative to Enhanced 911 service that is available on most traditional telephone service.
