Hello. I can assist you with your question.
This should set the ringtone on that phone.
To set the default volume:
Ringer Volume - While your extension is idle, press the VOLUME UP or DOWN button to adjust. There are 4 levels, and depending on programming, there may be a ringer off level as well.
There is a great quick reference for that phone at the following link:
I don't know what you mean by optionS, NEXT and RING. Where do you find these options?
Do you have the model number of the handset? I can be more precise if you can provide that. Thank you.
OK. Thank you. XXXXX have done is upload the user guide for that phone for you so you will have it for future reference. You can download it here:
Each of those is a button. There are interactive buttons at the top of the phone that change on the display depending on what you are doing.
This also includes a diagram of your phone with all the buttons labeled. The options button should be at the top.
