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.
Before either one can work you need to supply the Teleconsole with your iPhone number.
To do so, tap the Settings button 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.
The setting for iPhone Number is initially shows "Unknown". Because of the way iOS security is handled, the Teleconsole has no access to your personal phone number.
Tap Change and enter your personal mobile number manually.
Tap Change on the next screen to save the number.
On the Local settings tap Use Data For Outgoing Calls (VoIP).
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 iPhone 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 the Use Data For Outgoing Calls (VoIP) in Local settings you need to have either Always Use VoIP or Use VoIP only on WiFi selected.
When you experience any noise or statics 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.
