If you're having problems calling an ordinary phone number, this may be due to using an incomplete number syntax, a SKYPE account that has too little credit, and a handset that has lost its link with the base station. To resolve this, follow the instructions below.
If 00, + or 011 is omitted, enter "00", "+" (press and hold 0) or "011" before the number you are dialing.
If your SKYPE account has very little credits, purchase more.
Make sure the handset has a link with its base station. Pressing the PAGE button on the base station should enable the handset should ring and indicate that it's linked with the base station.
Note: If you move too far away from the base station while on call, an alarm tone will emit from the handset and the Base/Handset Link icon will flash upon its display screen. This means your call will be disconnected if you do not move back within the base station's range.
