If you’re working in a fixed location, it’s always better to use an IP Phone because they are always on, they are more comfortable to work with and reliable. Besides you can connect a headset or use the speaker to have your hands free when talking.
myPBX IP Phones are affordable and are shipped already configured for your convenience.
Smartphones and Tablets are practical, but if you forget to open the App you won’t receive any calls and there’s always a battery issue since it can run out when you need it the most.
Using a computer with a headset is also a good option but don’t forget to open the program to receive calls. Also if you don’t have a fast computer or you have too many programs running at the same time you may experience bad quality calls with robotized voice.
