SIP Trunking
Unlock The Power Of IP With SIP – One Connection to Thousands Of Calls Instantly
SIP is the key to unlocking the powerful potential of next-generation IP Communications. ThinkTel’s SIP-based solutions are tailor-made for enterprises that need or already have existing IP infrastructure and are looking to interconnect their sites with centralized PSTN Termination.
Connect to a carrier class network without investing time and money into devising a custom solution. Achieve significant cost reductions through a combination of “in-network” calling and line pooling across multiple locations.
By using ThinkTel native SIP trunks with your mediation server, you’ll not only see cost savings but experience telephony deployment in a whole new way. Instead of being locked in using traditional PRI's with fixed capacity and inflexible location requirements, dynamically assign capacity based on your business needs.
Superior SIP Based Solutions – Nobody Knows SIP Better! We Helped Pioneer It!
The creation of virtual phone lines between PBX and the public network is achieved by SIP (Session Initiation Protocol). ThinkTel’s strategy is to make the most use of existing network facilities and as such we are privately cross connected to most major Canadian IP network providers.

SIP unites separate devices and services across platforms, creating a seamless connection. SIP Trunking reduces or replaces traditional ISDN-PRI or analog business lines with a more efficient, flexible, and cost effective service. Once converted to SIP, calls to customers are transported over a combination of both private IP networks and the public Internet.
ThinkTel has been delivering SIP services since its inception. In fact, our engineering team contributed to the definition of how SIP is being implemented today. ThinkTel’s SIP-based solutions satisfy business objectives through a highly redundant and robust network with service in over 300 cities in Canada. Fixed line service can’t compete with the benefits of SIP by ThinkTel.
Shared Capacity Over Aggregate Channels
Aggregate channels across all locations and share a common pool. Dynamically allocate capacity allowing any one site to act as a complete failover /recover site. Assign local telephone numbers from any city to the main SIP trunk Group. Increase availability and survivability with redundant IP network transport and switching. And access multiple solutions to secure voice traffic including collocation of customer equipment in one of our switch centres.

ThinkTel SIP Advantages
ThinkTel’s innovations in service delivery and billing typically reduce overall monthly telecommunications costs from 30-70%. These reductions in cost don’t come at the price of reliability, either. SIP Trunking, when configured with multiple IP connections, is able to automatically or manually reroute call capacity via any other connection. ThinkTel is unique in that we support multiple network paths over diverse carriers and up to 8 simultaneous IP gateways.
Change Capacity At Any Time – No Penalties!
Manage capacity to your organization as an aggregated group instead of individually for each location. SIP expands in-network regions to include all locations as well as external or affiliated stakeholder organizations. PSTN access is only required to communicate with contacts outside of the company’s sphere of influence.
Change capacity at any time to ensure optimal usage and eliminate the expense of unused capacity. There are no penalties for changing capacity up or down and no limits on the number of times you can change it.
