[FAQ] How can I disable the message waiting tone?

An example configuration that can either be added via the => importing <= functionality of the Web Interface or loaded separately via a configuration file could look like this:


<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<!-- PlcmConversionCreatedFile version=1.2 converted=Thu Feb  9 16:50:43 2012 -->
<polycomConfig xmlns:xsi="" xsi:noNamespaceSchemaLocation="polycomConfig.xsd">
          <se.pat.misc.messageWaiting.inst se.pat.misc.messageWaiting.inst.1.value="0" se.pat.misc.messageWaiting.inst.2.value="0" se.pat.misc.messageWaiting.inst.3.value="0" />


Note: Please be aware that if you are running a SIP Software before UCS 3.3.0 you will need to check the Admin Guide in order to verify the commands.


UCS 4.0.8 added the following:


Parameter Permitted Values Default
mwi.reminder.enable 0 or 1 0


If 1, a Message Waiting Indicator (MWI) tone plays each time the phone receives an MWI update.

If 0, no MWI tone is played.


NOTE: Future UC Software 5.2.2 > will also include this Parameter !
