connect.37-dimensions.com ↗What the address means
A SIP URI identifies a SIP destination in the form username@host, optionally followed by :port. The host may be a domain or an IP address. It resembles an email address but routes a call rather than an email.
Using one entry with several numbers
The portal supports the {DID} placeholder, replacing it with the incoming number as listed in number management. For example, {DID}@pbx.example.com lets an appropriately configured receiving PBX distinguish which number was called. Match any required prefix to that receiving system’s numbering plan.
Prepare the receiving system
Create the URI entry, choose the relevant route and verify that the destination accepts calls. Confirm the host, port, network access and numbering format with support. A SIP address is not automatically a registered device, and entering it alone does not make an external PBX reachable.

Explore eligible support.
37D uses the same innovation-support mindset for its own eligible development work that it brings to client projects. If your Canadian business is undertaking qualifying R&D or developing an innovative technology, an SR&ED or NRC IRAP conversation may be a useful part of the plan.
SR&ED readiness
SR&ED provides tax incentives for eligible R&D carried out in Canada. Start by identifying the work, uncertainty, experiments, supporting records and expenditures that need professional review.
Explore SR&ED support →NRC IRAP readiness
NRC IRAP supports eligible Canadian innovation businesses through advice, connections and, in some cases, project funding. We can help organize a project and business-readiness discussion.
Explore IRAP support →A routine technology purchase, resale or implementation is not automatically eligible. Support depends on the applicant, work, costs, timing and program decisions. Other assistance can affect an SR&ED calculation, so the programs must be reviewed together rather than simply adding assumed benefits.
37D provides independent consulting; CRA and NRC make their respective decisions. No government endorsement, award or project-specific funding is implied. CRA SR&ED information ↗ · NRC IRAP information ↗.
Before you enquire
Is this suitable for my business?
Share your location, intended use and timing. The team confirms suitability, availability and the proposed scope before an engagement.
How do I get pricing?
Use the pricing enquiry with fast-track code C40028. Tell us the scope, location, expected usage or funding need and timing so the team can review the relevant costs and terms.
What happens after I enquire?
The team reviews your context and the selected service, then agrees a useful next step: information, a conversation, pricing or a partner discussion. An enquiry does not book a call or create a purchase commitment.
