How to set yealink IP phones ring longer, unlimited dialing and custom ringback tone.

[HijoTech]

Thanks Micheal,

If the yealink ip phone can't ring up to 24 hours then what is the maximum ring time of the phone?

I will want all callers to be on the call listening to ringback tone without puting their calls on “music on hold“ depending the maximum ring time of the phone in other to avoid callers being charged by their operators.

How possible is this?

Can yealink ip phone also enable video ringback tone?

thanks

Hi Micheal,

Going through the link their is no option to upload music as custom ringback tone.

Does it mean that one can't upload music to yealink ip phone to use as custome ringback tone?
