Using Your Conference Phone in SIP Mode
99
If you adjust the volume of a non-emergency broadcast, your phone retains the
adjusted volume for all subsequent non-emergency broadcasts. However,
even though you can adjust the volume of an Emergency broadcast, the
adjusted volume won’t be retained for subsequent Emergency broadcasts. All
Emergency broadcasts play at the same volume, until you adjust it.
Configuring PTT Mode
You can configure PTT mode by doing the following:
• Updating the default channel
• Updating channel subscriptions
• Allowing PTT broadcasts to play during active calls

transmit on the default channel, Channel 1. If you want, you can change the
