If you have problems calling via VoIP, check whether:
Your telephone is correctly connected to the SpeedTouch™.
Your telephone is working on the PSTN network:
Connect your phone directly to PSTN.
Try to make a phone call.
The call agent’s IP address and call agent’s port number are configured
correctly.
The PWR, PPP and VoIP Ready LEDs are on.

Your telephone is correctly connected to the SpeedTouch™.
Your telephone is working on the PSTN network:
Connect your phone directly to PSTN.
Try to make a phone call.
The Forced FXO service is activated, or whether your service provider
requested you to dial an extra prefix for making calls via PSTN.
As soon as the VoIP Ready LED turns on, you will hear a click,
indicating the switch from PSTN to VoIP.
If the SpeedTouch™ is turned off, phone calls are always routed over
PSTN.

FXO call, you will hear a click, indicating the switch from VoIP to
PSTN.
