Your smartphone,
as your company extension.
A cloud IP telephony app for remote work and large-scale deployments. Developed in Japan, and running on cloud services listed as secure by Japan's IPA under ISMAP.
A voice platform for remote work and digital transformation
Remote work and digital transformation still depend on talking to people: exchanging information in real time, carrying the meaning that words alone miss, and holding a team together. AGEphone Cloud connects to the major IP-PBX systems, so there is no large equipment project and no installation cost. Installing it on a smartphone is enough — which makes it a good fit for BYOD programs, shared offices and working from home.
iOS 26 Ready
Core functionality has been verified on iOS 26, with no effect on the main features or on how the app is used. Support for new capabilities such as the liquid design language is being added over time.
A financial institution moved
every branch to smartphone extensions.
Across all 76 branches, the customer retired its legacy PBX and moved to central cloud management as part of a digital transformation program, using NextGen's NX-C1000 for Enterprise IP-PBX and NX-B5000 for Enterprise SBC.

Central management
One place to manage the phone system, and room to add or remove capacity as needed.
Lower costs
Moving extensions onto company smartphones removed most desk phones and cut communication costs.
Answer from anywhere
With AGEphone Cloud, staff can take calls wherever they happen to be.
Office, on the road, at home.
All of it, on your extension.
A smartphone is enough to make and take calls on your usual company number. Freedom over where people work turns directly into how quickly the organization can move.
Pick the version for your platform
Enter the login details from your telephony service provider and the right configuration is delivered automatically (provisioning). You can skip the login and configure the app yourself, but that falls outside our support.
for Windows (commercial edition)
Paired with CallPicker, our free Chrome extension, a phone number on any web page becomes a one-click call.

An example: integration with JotForm
With cloud integration enabled, answering a customer call in AGEphone Cloud pops up a JotForm form with the caller's number and name already filled in. Pick the reason for the call, add your notes during or straight after the conversation, and the record is sent to the cloud service for whoever handles the next call. Combined with services such as Zapier and AirTable, the integration can go considerably further.
Using this feature requires a subscription to the premium service.
Secure, simple, efficient
Simple setup
Straightforward to configure, for administrators and users alike.
Strong security
Several safeguards for the day a device goes missing.
Works with our apps
Integration with the other applications takes another step out of daily work.
Low-power push
Calls arrive by push notification even when the app is closed.
Set up with a QR code
Provisioning keeps everything managed centrally in the cloud, so users never have to work through a complicated setup. Manual sign-in asks for only three things — tenant, user ID and password — and scanning a QR code finishes the job outright. The interface and manuals are in Japanese.
Security
- Hidden credentials (QR code sign-in only)
- Single sign-on
- Remote configuration update and lockout
- DR ready (SIP servers in geographically separate locations)
Everything business calling needs.
Close the app and still
catch the call that matters.
In a hotel on a business trip, or in transit. Extension calls reach you by push notification even when the app is not running. Battery use stays low while the phone waits, and with CallKit support on iOS you can answer straight from the lock screen.
Calling and operations
Call recording is included as standard. Recordings can later be put to use for AI transcription and for organizing your record of customer conversations.
Networking and quality
Integrations
Each cloud service requires its own subscription.
