There may be situations where poor Wi-Fi (or 3G/4G) reception will lead to static noise and call quality issues. To handle this problem you need to switch the TeleConsole to use your cellular network instead of a data network.
If you are nearby a landline you may also solve the problem by temporarily forwarding your number, as explained here.
There are two ways to switch the connection - permanently or on the fly.
For either one to work you need to supply the TeleConsole with your mobile number.
You can do this by tapping Switch in a middle of and entering your number at the prompt.
However, you may not want to be bothered with this in the middle of an important call. In this case you can provide your number in advance. To do so, tap the gear icon on the on the bottom-right corner to access the TeleConsole's settings.
The settings screen is divided into three categories - Channels, General, and Local Settings. Scroll down to Local settings, tap Device Phone Number, enter your personal mobile number and tap OK.
On the Local settings tap VoIP Settings and select Always Use Cellular Voice.
When selecting this VoIP will not be used at all until you switch to another setting.
With this selected, instead of sending the call to the Telebroad VoIP servers using the VoIP protocol, the TeleConsole will use your cellular connection for the call. Your phone will ring (outside the TeleConsole) and when you pick up the outgoing number will be dialed. Remember that this setting consumes your mobile plan air time minutes!
On the Fly Switch
On VoIP Settings in Local settings you need to have either Always Use Voip or Use Voip only on WiFi selected (assuming you are on a WiFi connection).
When you experience any noise or static during call a call, tap the Switch button on the call screen to change to the cellular network.
Tap the button again to switch back to VoIP.
