【實用工具app】Dialer|最夯免費app-綠色工廠好玩App

Dialer works with any Plain Old Telephone System (POTS) Landline phone that accepts DTMF tones. Pressing a button generates a DTMF tone which tells the telephone system to dial that number. To dial, you hold your phone's speaker up to a telephone handset or microphone and play the tone by pressing a button or by using quick dial.Quick Dial allows you to store a calling card number or teleconference number for quick dialing on a landline, simply hold up your iPhone speaker to the landline telephone's microphone or handset and press dial. Commas act as pauses during the dialing tone sequence to allow time for prompts and other delays.**Please note that some Voice over IP (VOIP) systems can have trouble recognizing the tones, for those systems try a longer key press allowing enough time for the system to register the tone.
