Offer your customers IP Centrex, voice and video calls, conferencing, unified messaging, and presence service with PortaSwitch

PortaSwitch maximizes your efficiency as a cloud PBX provider

Cater to enterprises' needs

What are the business drivers that lead enterprises to consider IP Centrex? PortaSwitch caters to all three motivations:

  • Replacing a legacy PBX in order to simplify maintenance, enable remote offices or work-from-home employees to function in a single environment
  • Migrating from another IP PBX solution to gain better flexibility, reduce costs
  • Increasing staff productivity through CIT (computer telephony integration), which typically means integration with CRM, auto-dialing, access to call recordings, etc.

For our operator partners, the advantage we offer is the independence to run their businesses so that they are most attractive to their customers. PortaSwitch allows us to do this. The important thing for me with PortaSwitch is its stability.”

Customize your revenue stream

You have the power to define your service offer as a combination of recurring fees per line, charges to be applied based on the total number of extensions, per-minute calling rates, bundled minutes, volume discounts, so on. You can offer “à la carte” subscriptions for specific features on top of the basic plans. The options are endless so that you can create what works for you and your customers.

Get your customers set up quickly

When a customer is created in PortaSwitch, administrator picks the desired product combination and enters the financial parameters (such as credit limit, payment terms, or fraud-detection profile). This defines which platform features customer has access to, how the system will charge for the usage (e.g. phone calls) and how it will assess the recurring charges—either fixed or based on the number of extensions. Alternatively, customers can activate their services independently via online sign-up portal.

The administrator allocates IP phones from the CPE inventory to the customer. This means that for more than 50 supported models of phones as soon as an IP phone is connected to the network it is automatically provisioned by PortaSwitch, with no further action required on the customer side.

Customers are assigned login credentials for the self-care portal, so later on they can configure their extensions, huntgroups, auto attendants, obtain additional local/toll-free DID numbers, purchase add-ons such as call recording or conferencing.

High end security and reliability

PortaSwitch supports SIP over TLS and ZRTP, so all communication between a phone and the server is encrypted and secure. When an end user makes an outgoing call from the customer’s office, the call is authorized by PortaSwitch: various fraud-prevention measures are applied, and the customer’s balance is checked in real time. PortaSwitch then routes the call to another cloud PBX extension (for intra-office calls), or to a PSTN network.

Calls to DID numbers (local or toll-free) arrive from carriers or DID exchanges, and are then routed to an auto attendant, call queue, huntgroup, or individual extension, depending on the settings. Fax-over-IP, both outgoing and incoming, is supported as well.

When customers use the service from the office, at home or on-the-go, the advanced NAT traversal capabilities of PortaSwitch allow them to connect calls regardless of the specifics of the network configuration.

Hosted IP PBX integrated billing

PortaSwitch is a service delivery platform for hosted IP PBX that streamlines your business end-to-end. Inside their portal, your customer has a clear overview of all configuration settings, call recordings, CDRs and invoices. What’s more, each employee has access to the self-care portal for his individual line and can monitor their usage or configure settings such as follow-me numbers.

PortaSwitch revenue assurance means that no call is allowed when the balance is insufficient; every call is immediately charged and applied to the customer’s balance; every feature activation / deactivation is directly linked to the billing.

At the end of the month, all applicable fees are assessed, a PDF invoice is generated and emailed, and the credit card on file is automatically charged.

Architecture of a hosted PBX platform

hosted pbx

PortaSwitch is a unified service delivery platform, which includes the following components:

Session border controller (SBC)

SBC provides a high-availability control point for all network communications. It hides the internal network topology, provides NAT traversal, protects from denial-of-service (DoS) attacks, limits call initiation ratio per end-point, automatically distributes traffic between available softswitch nodes, and enables multiple transport protocols (e.g. SIP over TLS).

Softswitch cluster

Highly scalable class 4 and 5 SIP softswitch delivers call control and media processing functions. It supports real-time call authorization and charging, dynamic call routing, advanced call control, full cloud PBX feature set, voice and video calls, fax-over-IP, presence / BLF, instant messaging and SMS. Media processing includes voicemail, auto attendant, call queues, call recording, IVR applications, voice and video conferencing.

IP phone auto-provisioning

Zero-effort instantaneous configuration of more than 50 different IP phones from various vendors. Flexible provisioning framework allows customers to easily add new phone models.

WebRTC gateway

This optional, third-party technology allows you to deliver feature-rich communications directly to your customer’s web browser.


Easily configure service parameters, set up recurring and usage-based charging, and activate customers. You can also monitor and troubleshoot, as well as send invoices. With a real-time data link between BSS and softswitch, any changes go into effect instantly and require no additional configuration.
You can implement a variety of revenue generation methods, such as “all inclusive” or “a-la carte” selling of features, selling bundles of minutes for monthly subscriptions, or charging based on metered parameters.

Self-care portal

Our user-friendly portal makes it easy for the customer to perform most of the cloud PBX configuration, such as adding extensions or configuring hunt-groups. Customers can also access CDRs and invoices, make payments, and handle other important tasks all on their own.
