About this app

EQU-A-PHONE is an app that lets you use your Android smartphone as your company phone.

You can make and receive calls using your company number with just your smartphone, without needing a landline in the office.

You can make calls just like you would with your regular company phone, whether you're working from home, out on the go, or on a business trip.

■ What you can do

● Your smartphone becomes your company phone
You can receive company calls that you previously received on your landline, right on your smartphone. Outgoing calls also use your company number, so your personal number won't be displayed to the recipient.

● No need for a landline or wiring
There's no need to place a phone on your desk or run phone lines. As long as you have a smartphone and an internet connection, you can use it as your company phone anywhere.

● Equipped with commonly used business phone functions
- Hold/Transfer/Park Hold (Temporarily put calls on hold and answer them again on another smartphone)
- Call Recording (Manual/Automatic)
- Call History/Missed Calls Check
- Call Waiting (Receive incoming calls while on another call)

■ Recommended for those who:
- Want to remove their landline and handle all business calls using only their smartphone
- Work from home or are often out of the office and don't want to miss calls to the company
- Want to use their company smartphone as an extension terminal for sales and support work
- Want to reduce the operation and wiring costs of their telephone system

■ Important Notes on Use

This application cannot be used independently. The following two items are required for use:

1. A SIP-compatible IP-PBX (telephone exchange)
2. A service account for this application (user ID, password, etc.) issued on that IP-PBX

These must be provided by your company's system administrator or the service provider that implemented the system.

Please note that individual customers cannot log in or make/receive calls by installing the application alone.

Companies and businesses considering implementing this application should contact the application provider.
Make calls with your smartphone. No need for a landline phone.
