Gigaset Options

By default, conversations between your device and the Voys telephony platform are unencrypted over your network and the internet. By using encryption, your conversations are encrypted only between your phone and our platform.

Both SIP packets and the audio itself (RTP) can be encrypted. This ensures that no one can listen to your conversation by intercepting network packets. We use TLS for encrypting SIP packets. The RTP audio is secured using SRTP.

This guide only describes how to set up encrypted calling. If you want to know how to set up a device in the regular way, click here.

Setting up your device for encryption

‣

First you need to find the IP address.

• Press the Help button on the device.
• Go to the IP address displayed on the phone using a web browser.

Click on the link Identity 1 in the menu and go to the Login tab.

• For Registrar and Outbound Proxy enter sip.encryptedsip.com:5061;transport=tls
• Click on Apply.

‣

Go to the RTP tab.

• For Codec enter pcma, g722, g729
• Change RTP/SAVP to mandatory.
• Click on Apply.

You are now making encrypted calls between your phone and the platform.

Is my device encrypted?

You can quickly check if your devices are encrypted using the following method:

• Log in to Freedom.
• Go to Admin.
• Go to VoIP-Account.
• Go to the VoIP-Account of the device in question. If you see a lock in the green dot, then it is encrypted. If not, it is not encrypted.

There are three ways to trace the IP address of the phone, both via the handset and via the base station (N510 or N300).

Once you receive a call, you can transfer it to another device. It's possible to transfer to internal numbers (For example 201, 202 etc.) or to external numbers (mobile or fixed numbers). You can transfer with consultation (where you speak with the other party first, e.g., your colleague) or you can blind transfer (you transfer the call directly to the other device).

Would you like to be able to tell from the ringtone whether you're being called by a colleague or a customer? This guide explains how to set up an internal ringtone for your desk phone, so that an internal call gets a different ringtone than an external call.

For this device, you set the internal ringtone via the handset

• Go to Menu.
• Go to Settings.
• Click on Ringtones (Handset).
• Click on Melodies.
• Set the appropriate ringtone for internal calls and the SIP account being used.
• Make sure you add the “alert-internal”, so the phone knows which calls are internal. Read more about the distincive ringing on this page.

When you're on a line with a call and you receive another call, you'll hear a beep tone through the line. This can be distracting, so in some cases it might be better to disable this. You won't then receive a notification of a new call when you're already on a call.

The following guide is for the Gigaset R650H/S650H.

• Press the menu button on your handset.
• Go to Select Services/Network services and press Ok.
• Then click on Call Waiting/Call Waiting.
• Change the status to On or Off.

Resetting the handset with codes:

• Turn off the handset
• Hold down keys 1, 4, 7 and turn on the handset
• Enter 76200
• The handset will now be reset to factory settings

Turning off via the Web interface:

• Go to Settings.
• Then to Telephony.
• Finally to Audio.
• For Allow 1 VoIP call only change No to Yes.

• Go to Settings.
• Then to Telephony.
• Finally to Sound.
• For Allow only 1 VoIP call change No to Yes.

• Go to the Menu.
• Select Settings.
• Then System.
• Under Local Area Network select Type IP address.
• Here you set Dynamic instead of Static.
• Click on Save.

There are multiple ways to set up an address book on a Gigaset device.

Sometimes you don't want to be disturbed by your phone. You can then set your device to do not disturb mode.

Gigaset handsets do not have a separate 'do not disturb' function. What you can do is turn off your handset. You can do this by holding down the button with the 'red handset' icon.

When you switch off your handset, all incoming calls that normally would ring your handset will be rejected. Depending on your call plan, the incoming call proceeds to the next step in your call plan.

Tip: Change the softkey on your device to 'dnd'. Press the button on the top left or right of your handset until you see a selection screen. Click on 'do not disturb' and you can now set your device to 'dnd' more quickly!
