Ring timeout

[HijoTech]

Hi,

Please i will want you to help me clearify my enquiry about how i want to use yealink ip phone to carryout a project.

I will like to create a “call to listen music“ kind of service using Yealink IP phone. I will want unlimited callers to call the phone at the same time enabling all numbers dialing the phone to ring up to 24 hours enabling them to listen to music jamz set as ringback tone for free without the callers being charged by their network operator. Please make your comment on the following questions below.

Can Yealink phones accept unlimited calls dialed at the same time?

Does Yealink phones enable custom ringback tone?

Can one stream live audio to Yealink phones so as to use it as ringback tone?

stream live audio to Yealink phones so as to use it as ringback tone?

Can Yealink phone set to ring 24 hours and end the call once the 24 hours of ringing elapse?

Does Yealink require internet connection to enable it work?

I look forward to hear from you.

Thanks
