C Spire Push To Talk is now available on certain Android and BlackBerry smartphones, and it's easier to use and manage than ever before. The PTT app offers a highly scalable and simplified approach to PTT administration and security.

The Push To Talk app provides security through voice and signaling encryption over WiFi and cellular using the Advanced Encryption Standard (AES) 256. This protects PTT users from unauthorized call interception and monitoring, and provides secure alerting and contact management.



Large PTT Contact & Group Capacity
C Spire's PTT application leads the industry with contact and group capacity.

  • 1,300 Contacts in your PTT address book (1,000 managed by an administrator, 300 managed by the device user)
  • 130 Talk Groups (100 managed by an administrator, 30 managed by the device user)
  • 250 members per pre-defined group managed by an administrator and 30 members per pre-defined group managed by the device user.

Contact Capacity Display
A convenient contact capacity display makes it easier to manage your contacts and talk groups on your device. The capacity display indicates the total number of contacts so you'll never lose track when adding to your PTT contact list.

Automatic Contact & Group Synching
When an administrator makes changes to a contact list or group, the information is pushed over the air to your phone automatically and in real-time.

Special-Purpose Talk Groups
Create special-purpose talk groups so you only communicate with the people you need to when you need to. No more "broadcasting" a message meant for one person to your whole organization.

Quick-Group Calling
Call up to 10 contacts from your PTT contact list at the same time for a quick-group call. Just select the contacts and start the call. Your call will be transmitted to all the selected contacts simultaneously without the need to create a pre-defined talk group.

PTT Caller Availability
C Spire's PTT application lets you know if someone is available to talk before you push the button. The app shows an icon next to each contact indicating their status: Available, Busy (Do Not Disturb), or Offline (powered off).

Fast Presence Switching
When you need to change your presence status, simply select your status option from the PTT application's Home screen. Any change you make in your presence status shows up immediately on other users' devices.

Contact List Sort/Filter
See which of your co-workers is available with a glance at your Contacts list. C Spire's PTT allows you to easily sort and filter contacts based on availability, name, and/or phone number.

Set Your Own Favorites
Add the contacts and talk groups you call the most often to your Favorites. With all your Favorites collected in one place, the C Spire PTT application makes it faster and more efficient for you to make PTT calls to the exact contact or group you want.

Hold PTT Calls for Cellular Calls
If you receive a regular cellular call while you are on a PTT call, you can put the PTT call on hold. Once you finish answering the cellular call, you can easily go back to the PTT call.

Call History
The C Spire PTT application home screen provides a convenient list of the calls you've made and received. It's easy to call someone back, review the call log, or send a call-me alert.

Missed Call Alerts
PTT users receive an alert each time they miss a call. The alert shows the contact information and time of the call. Users can initiate a callback directly from the alert.

Send Call-Me Alerts
If you want to call a contact whose presence status is "Do Not Disturb", you can send a Call-me alert without the need to leave a voice mail or type a text message. Contacts instantly receive the Call-me notification even when they are not available to talk.

Fast Call Backs
If you receive a Call-me alert, you can initiate a call back directly from the alert. Simply press the "Call" button on the alert notification.

Idle Phone Call Receive
Even when your phone is idle, an incoming PTT call will immediately wake up your phone and allow you to hear the caller's voice. No action required. If you need to answer the call, just press the call button when the caller releases the call floor.

Talker Identification
When you are on a group call, the person talking is identified on the screen of your device. If someone else takes the floor, the information will update automatically.

Log in to the Centralized Administrator Tool. Administrative access is required.

Accessible from Anywhere
The Centralized Administrator Tool supports all commonly used web browsers, including Internet Explorer 8 or 9, Firefox 8, Safari 5, or Chrome 15. No software installation is required. Wherever the administrator has an Internet connection and a supported browser, they can access the Centralized Admin Tool.

Program Phones before Deployment
After an organization adds the PTT feature to their account, an administrator can assign contacts and groups to PTT users before handsets are deployed and activated. This allows end users to immediately start using PTT when they receive their handsets.

Empowers Your Organization
With the Admin Tool, administrators gain direct control and more flexibility over how PTT is used within the organization. They can create, assign, and remove a temporary talk group on the fly without the involvement of C Spire customer care or the need to physically obtain devices. Admin can make changes to the PTT communications structure in real time.

Build & Assign Talk Groups
The Admin Tool enables administrators to easily create and modify talks groups. Administrators can build talk groups of up to 250 members from within the web portal. Since the Admin Tool only displays PTT users for the specific organization who have the PTT feature, list of contacts will have only the members they need to build the talk groups.

Real-time Wireless Sync
Contacts and talk groups assigned to PTT users are automatically pushed out from the web-based Admin Tool to devices wirelessly in real time. No human action is required on the devices to accept the updates. When an admin makes changes to a PTT user's contact list, moves or adds the user to different groups, or modifies the name of a PTT user, the updates are pushed to all devices in the group immediately so PTT users in the field are always up to date.

Allocate PTT Contacts
Easily allocate contacts to each PTT user without the need to physically interact with any PTT devices. The Admin Tool shows a master list that contains all of the organization's PTT users. The tool also allows administrators to add and assign external contacts who use C Spire PTT to the organization's PTT users, such as a supplier or contractor.

Lock Down PTT Devices
Administrators can prevent individual users from creating or saving additional PTT contacts or groups from within the Admin Tool by setting the user to "Corporate" mode. In Corporate mode, only the centrally-managed PTT contacts and talk groups are available on their devices. PTT handsets and devices automatically switch to Corporate mode when the setting is changed within the Admin Tool.

Manage All PTT Apps
The Admin Tool allows administrators to manage all the contacts and talk groups for all PTT users regardless of the device platform or subscriber type. That means that any of the PTT apps for Android, BlackBerry, or soon to be released iOS devices are manageable from the convenience of the Centralized Admin Tool for PTT.

Adapts to Your Organization
The PTT Admin Tool is highly scalable and designed to meet the needs of different types of organizations and different internal structures. The tool adapts to the business's PTT needs and allows a small business to be agile and flexible or mirror the strict structure of a larger multi-national corporation.
