An IP (Online Protocol) mobile phone employs an World-wide-web connection to spot and acquire telephone calls. You may use practically any model of land-line cell phone as an IP telephone by connecting the products to a VoIP (Voice over World-wide-web Protocol) box, that is provided by subscription service providers including Vonage and Skype. Including external speakers requires a phone equipped with an audio output jack, including for any headset connection. You are going to need to use a self-powered external speaker, since the Line Out jack on an IP mobile phone does not create sufficient energy to drive a speaker. 1.Set the speaker on a level surface inside of connecting distance with the IP mobile phone. 2.Insert the 3.5mm plug on one particular finish from the audio cable to the Headset or Line Out jack over the IP phone. 3.Connect the plug within the other finish of your cable for the jack about the rear with the speaker. 4.Insert the DC power plug to the speaker’s electrical jack and connect another end to a wall outlet.
