How to get started using your Cisco 89xx phone after it is installed.
1. Dial 8 ( or 9) to get an outside line. Example: to call your cell phone, you would dial 8+1+[10 digit cell number], or if your cell number is a local number you could simply dial 8+[7 digit cell number
a. To call another employee at your organization, you may dial their 4-digit extension, or if you don’t know their extension, you may dial 0 and then speak their name (as it would be listed in the corporate directory).
2. Phone Support: If, after reviewing the initial training sessions or reviewing the available online help (videos and hands-on), you have questions about using your phone or other CallTower services, contact your local CallTower administrator.
