Hello & Welcome to Just Answer,
I'm Greg and will do my best to assist with this issue today.
Sorry I didn't see your question earlier and to hear of any issue you are having with your phones or voicemail service.
To help you with this issue, may I ask:
1) The FULL Model Number of the phone system you are working with? If this is a cordless system, that model should be printed on a sticker on the bottom or back of the MAIN base unit (model should start with KX-TG).
2) What phone service provider (phone company) you have for this phone line?
3) What are you trying to "put in" the voice mail system (I think you left out a word or two above)?
Please REPLY using the box below and the SEND button.
*** IMPORTANT NOTE: *** ANY requests for "additional services" (such as a phone call) are OPTIONAL and sent BY THE SITE AUTOMATICALLY (and not me), and I'm NOT be available by phone at the moment.
Feel free to DECLINE (close) any such offers, and continue in this text/chat form.
