Grandstream Wave softphone features

1. Call transfer

Grandstream Wave may be the only free smartphone that allows you to make 2 kind of call transfers:

• Direct/blind call transfer
• 2 step call transfer: before transferring the call, you speak whith the receptor first

This one is a really important feature in a softphone for an enterprise.

2. Conference

There aren´t many free softphones that allow you to make phone conferences and, again, Grandstream allows you to make them.

When using conference you will be able to have a conversation with up to 5 people on the same phone call. This way you´ll save time speaking with all at once. Furthermore, conferences save the phone numbers you included so that you don´t have to dial them the next time.

3. Call divert

You can divert phone calls directly with this softphone and do it even based on the time.

4. Mute / Hold

While you are on the phone you will be able to hold the phone call or silence it (mute). These 2 functionalities are really useful when you need to ask something to a colleague.

5. Always working

If you are not using your smartphone and someone calls you to your VoIP phone number the softphone will receive the incoming call and your phone will ring and vibrate.

This indispensable feature is not available in every softphone and Grandstream do has it. And that´s a reason why we love it.

How to configure Grandstream Wave Softphone on iPhone and Android

Problem Solving with Grandstream Wave

1.My account it´s not registering, it´s still in red

By default the app it´s only working when connected to WiFi. In order to use it when you are not on WiFi:

Settings → Advanced Settings → WiFi Only: desmarca esta opción.

If your VoIP account is not registering, make sure all the data is correct. 99% of times an account does not register is because the user, SIP server or password are not well written.

You have to write in both SIP User ID and SIP Authentication ID your Telsome's VoIP extension: xxxx*xxx (4 dígitos, asterisco, 3 dígitos).

2.They can´t hear me

When you first active Grandstream Wave the app asks you for permission to use the microphone. If you no not accept your microphone won´t be working with the app and they won´t be able to listen to you. You can change this from the settings of your smartphone.
