We manage the network so you manage your sales

Wholesale SIP Trunking

Coast to coast network footprint

ThinkTel is the ideal partner for voice providers operating their own switching infrastructure who are looking for cost-effective ways to expand their business. We leverage existing network facilities and, as such, are privately cross-connected to most major Canadian IP network providers. Any properly designed IP network configuration can be supported, including multiple VPN connections and direct colocation of equipment to our data centre. Rely on our CLEC network infrastructure and wholesale SIP Trunking services for both origination and termination of your traffic.

The ThinkTel CLEC network infrastructure delivers service to over 1,700 Canadian Rate Centres. Our network utilizes TDM transport in all centres and delivers SIP over a combination of both private IP networks and the public Internet.


ThinkTel utilizes Metaswitch VP3510 softswitches providing a 1:1 ratio of digital signal processors to PSTN call paths. This means that we can deliver 100% of our network capacity using any one of the available compression codecs that we support. Our Metaswitches also support geographical diversity at the media gateway layer and at the signalling layer to ensure network resiliency and survivability.

Contact us to discuss how you can dynamically increase revenues by delivering high-quality, low-cost services to households and businesses.
