How do people play music to the caller instead of a ringing sound. Or like play music to people who screen their calls. If you don't know how can you tell me the name of what it is. Cheers
Verizon has a service called "Ringback Tones", that's the most popular for cellular devices. I don't know if that's what your looking for though.
For att its $2.99 per year its called a Answer Tone. Call back tone for sprint. You have to go online with your phone to get em.
