Hi again and thanks for that information.
OK - I looked up that model number, and I have a link to the manual for that model below, in electronic (PDF) form. It should appear on your screen when you click the link.
Click here --> CS6219-2 Manual
Now I also notice that this system does NOT have a built-in Answering System, and the only "feature" it has related to Voicemail is that it does have a "NEW Voicemail" indicators - on both the Main Base unit and a message that displays on the handset (see pages 7 & 10 of the manual).
There is also a "Clear Voicemail" feature that turns OFF the indicators, if the voicemail messages were listened to from a different location, or from a different phone in your home (see page 10).
So IF you have voicemail from your service provider (Suddenlink in this case), any "setup" to turn ON the system would be controlled by the provider, and to access that system, you would simply "dial in" to get into the system, and you would need a pass-code (or PIN) to listen to the messages. Once all the new messages have been listened to, any signal being sent to your phone should be turned OFF, and the indicators should also turn off at that time.
So there is no real "setup" on the Vtech phone itself - just the indicators that tell you there is a new message waiting.
As a reference, I have a link to the Suddenlink Voicemail setup help page, that gives you the basic steps for setting up the system, if you have not set it up previously. If you need to contact the Suddenlink folks directly about the voicemail system, I believe there are also links on that page under the "Contact Us" heading.
I hope this helps give you enough information to get your Vtech connected and explains a bit about how it would work with the service provider's voice mail system.
Please let me know if you have any more issue or questions.
And when you are ready, please take a moment to rate my service level (Excellent is my goal) so that I get credit for helping you today. You should see some "smiley faces" or "stars" to do that, but please let me know if you do NOT see them or can not use them.
Thanks, ***** *****
