Canada's Largest Privately Held Carrier

Over the past decade, Comwave has become Canada’s leader in wholesale VoIP services. More phone companies rely on Comwave VoIP services than any other.

With a full portfolio of products to support small and large wholesale opportunities, Comwave is ideally suited to help you with A-Z Termination, 9-1-1, LNP, SIP, Local Access and much more.

Comwave's wholesale SIP Trunking gives you an easy and cost-effective way to achieve local DID origination and call termination throughout Canada, the US and overseas. Access 192 Canadian rate centers, 1,500 US rate centers and 24 countries overseas – all on one aggregated SIP channel.


We have several different types of trunks to choose from:

Regional-Flat rate Unlimited Local

This is a great replacement for a traditional PRI for a specific rate center Eg. Hamilton Ontario. For a flat monthly fee you can originate and terminate as many minutes as you would like for that rate center. Comes as both Uni-directional and Bi-Directional.

National-Flat rate all of Canada

There is no better way to originate and terminate calls across Canada. With a single National Trunk you can assign a DID in any rate center in Canada and terminate anywhere in Canada for a flat monthly fee. You never have to worry about augmenting capacity in every city, and you get to maximize utilization of your Trunk.

Eg. Lets say you have customers in Hamilton and Toronto and all of a sudden you have an opportunity in Vancouver. With National Trunking you need just one trunk for all the cities where with regional or traditional PRI you would need a trunk in every city which leaves unutilized capacity idle in each city.


Comwave provides DID origination in 1500 US cities across the United States all on a single aggregated SIP trunk. When buying Wholesale Carrier Service from Comwave, you can be assured that your DID and SIP Trunking requirements across North America can be covered by a single provider.


If you have a need for DID origination beyond North American borders, Comwave can provide you with the phone numbers you need in 24 countries abroad all on a single aggregated SIP trunk. Speak to us about our growing coverage throughout the world.
