Direct Connect Tips
When using Direct Connect, it is important to follow some basic push-to-talk etiquette to avoid annoying those around you and to avoid interrupting other users when they are in situations where a Direct Connect call over the speakerphone is not appropriate.
When making a push-to-talk call, ping before you speak.
The considerate way to call initiate a Direct Connect or Group Connect call is to first ping the other user(s) by pressing and releasing the push-to-talk button, then wait for a response from the other user(s) before continuing the conversation. The "pinged" user on the other end will hear a chirp and see the name or number of the caller (or group) on their screen. If the other user is available to speak, he can then respond back and the conversation can begin.
Unless the other user is known to be in a situation where an incoming push-to-talk call is expected or acceptable, it is inconsiderate to begin a call by just pressing the button and immediately speaking (such as “Hey, are you there?”). This approach results in the caller's voice blurting out over other user's speakerphone.
Quiet your incoming calls
When in a situation where you don't want your incoming push-to-talk calls to disturb others, make sure your speakerphone is off and then turn off your phone's ringer by selecting the Vibrate option. Your phone will buzz discreetly when the call comes in.
Maintain your privacy.
By default, push-to-talk calls are broadcast over your phone's speakerphone. However, if in a situation where you want more privacy for your conversation or where the speakerphone could disturb others, you can turn off your phone's speakerphone feature and use the push-to-talk with your phone's earpiece or with an ear bud.
Use Call Alerts judiciously.
The Call Alert feature lets you send a ping to another user to let them know you want to reach them. Adding a sense of urgency, the Call Alert will repeat until the other user responds. Considerate use of this feature is to use it sparingly and to ensure that whom you are alerting is near their phone. Others can be easily annoyed when their co-worker's phone is unattended and chirping repeatedly.
