BT’s ISDN Switch Off – What this means to you

Fax to Email to Fax

Streamline faxing by sending and receiving faxes via email, reducing consumable costs and filtering out unwanted junk. Additionally, you can email documents to an outbound fax service and transmit emails to someone’s fax machine.


Voicemail is available when calls go unanswered, either through failover for compatible extensions or direct routing, such as time-based routing for out-of-hours situations.

On Hold Music / Message

You can upload custom on-hold music or messages to the system, ensuring that when you place a customer on hold, they hear your tailored music or marketing message. Alternatively, you can stream content from a service or server, for instance, like a radio station broadcasting while the caller is on hold.

FSA & PCI Compliant Call recording

All call recordings are automatically saved for 60 days and are included in the standard extension cost. However, longer retention periods can be specified, with additional storage charged on a per GB basis. One minute of recording occupies 0.25MB. Customers have the option to download bulk call recordings for specific timeframes. Moreover, agents can pause and resume recording during calls when obtaining payment card details.


Our conference service offers a single number for clients to dial into multiple conference rooms. These rooms can be monitored via the web portal, featuring functions like viewing participants, muting all attendees, removing individuals from the conference, enabling/disabling call recording, and activating/deactivating announcements.


Phones feature log in/out capabilities, facilitating hot-desking. Direct Dial In (DDI) numbers remain associated with the logged-in user, not the physical phone.

Call Block

You can block calls or direct them to voicemail based on their caller ID.

CLI Presentation

We endorse the presentation of registered numbers from a company’s address database and also support presenting withheld numbers on the platform.

WLR 4 (SIP Trunks)

WLR 4 replaces ISDN, providing advanced features such as call recording and time-based routing, often used with remote hosted seats for unified systems.

Voice policies allow control over users’ call expenses by restricting certain extensions to low-cost call types, following the designated calling matrix.

Credit Limits

Credit limits are preset per user and company, preventing excessive charges with configurable alerts and call barring.

Auto Provision Devices

Auto-provisioning ensures device security and uniformity. We swiftly update software, syncing portal changes with handsets, simplifying client rollout and support.

Alternative CLI

You can easily configure your phone to display different numbers with a single click or by using a short code. This is especially useful for representing multiple companies or different business areas.

Fraud Prevention

Our system actively combats toll fraud, a prevalent issue. Continuous analysis, triggers, and 24/7 monitoring swiftly thwart high-value fraud, often originating from compromised network phones. Auto-provisioning is crucial for added security, and early intervention helps prevent significant phone fraud incidents.
