Build a DID trading platform using PortaSwitch

Resell inbound DIDs (local, toll-free, premium and international) to call centers, enterprises and residential customers. Manage DID inventory or use on-demand number acquisition to reduce costs.

What is DID management?

Manage local, toll-free and international phone numbers (aka DID – Direct Inward Dialing numbers) to be delivered to your hosted PBX or SIP trunking customers. Enjoy flexible monetization based on volumes of minutes, trunks, numbers, etc. Take advantage of rich features such as customized call flows via API and easily integrate with your CRM via low-code tools that automate and streamline repeated functions and tasks.

Quickly and easily build integrations with systems that provide phone numbers, reducing the hassles you suffer each time you want to offer your customers DIDs from a new country. Plus enjoy the flexibility of defining your own markup price and each time you offer your customers other countries’ DIDs, use the same configuration.
Set it and forget it.

How does it work?

PortaSwitch is constructed to provide high-availability, high scalability, and be highly efficient. Technologies allowing you to deliver content and charge for those services, all in one interface:


processes calls from carriers, does manipulation of SIP messages (to allow delivering calls to PBX systems what are not fully compatible to standards)

On-demand DID provisioning modules

connects to DID aggregators via API to instantly obtain new DID numbers (or release numbers that free up).


performs call authorization and charging (including toll-free and premium number payback charging)

DID inventory

to keep track of all DIDs and their cost/revenue and provision on demand or uploaded from a file

Self-care portal

allows customers to perform DID configuration, access CDRs and invoices, make payments, and more.


6 Steps to Provide and Monetize IPTV services ​


Choose how to start

Buy DID numbers in bulk from local telcos and import into DID inventory in PortaSwitch. Sign up with online DID providers. PortaSwitch will reserve and activate numbers when your customer requests a number.


Configure products

Include charges for DIDs plus per-minute charging (e.g. for toll-free numbers), pay-back charging (when you pay money to the owner of the number for processed calls, e.g. for premium numbers), recurring subscription fees, charges based on the number of used SIP trunks / active calls, bundle discounts, etc.


Configure & connect user

Create a customer in PortaSwitch and configure accounts underneath it to authorize SIP trunks to the customer's IP PBX or call center system. Once the customer enters these credentials into their system, they are ready to receive inbound calls.


User self manages

Customers can purchase additional numbers and change forwarding settings for specific numbers via the self-care portal.



Customers receiving inbound DID calls to an “old” IP PBX or less-than-perfect cloud PBX platform, have an option to connect their IP phones directly to your PortaSwitch and start using it as their hosted PBX.


Embed DID provisioning

Using PortaSwitch API you can embed DID provisioning into any portal or applications, or even allow your customers to do so (e.g. large call centers would request / release numbers autonomously). Or use call control API to do dynamic call routing Solution Components

What makes our PortaOne solutions special?

Act fast!

The way of doing business has become increasingly global in recent years.

Chances are your customers are operating in multiple countries and need virtual numbers on demand.

Provisioning, managing, and charging for such services can be difficult without the proper software platform.
