Web call enables you to make calls on the device's web interface. It can be used to test remotely whether devices can make calls normally.
Take R29 as an example.
Steps
Use the device IP to log in to its web interface. The default username and password are admin.
Go to System > Maintenance > Web Call interface. Enter the SIP number or IP number.
Note
To make IP calls, make sure:
The calling and called devices are within the same local network.
Direct IP call feature is enabled on both sides. It is enabled by default.

Select the registered SIP account to make the call. If both accounts are registered and you select Auto, calls will be made by Account 1.
Tip
See how to register a SIP account: Register SIP Account on Akuvox Door Phones.
Click Dial Out to make the call and end the session by clicking Hang Up.
