Telephony Protocol
Telephony Protocol lets you select the VoIP protocol that your site is
licensed to download and run. The SIP protocol used for the NEC
MH150/MH160 Mobile Handsets requires license option selection 36.
Any other protocol will cause the handset to malfunction.
Push-to-talk (PTT)
PTT is disabled by default. When enabled, all 24 PTT channels are
allowed by default. To toggle the allowed status of any channel, select
Allowed Channels, scroll to the channel to be disallowed and press
NavOK. Allowed channels are displayed with an asterisk (*) in the left
column. Only those channels allowed in the Admin menu will appear on
the Config menu where they can be subscribed to by the end user. The
priority channel, labeled by default as channel 25, may be set and will
be available to all PTT handsets. When a PTT broadcast is made on the
priority channel, it will override any active PTT transmission on all other
channels.
Time Zone
Worldwide time zone options are available. Greenwich Mean Time (GMT)
is the default.
Daylight Savings
The handset may be adjusted for daylight savings time.
