Exit and save, the handset will now try and register to the SV9100.
If it fails it may be because the router does not support dynamic address and port mapping. If this is the
case Static NAT may have to be used.
SIP MLT Time Zone Offset
If a SIP MLT is located in a different time zone to the system it is registered to the time and date may be
incorrect.
This can be resolved by offsetting the time and date on each handset compared to the system. Use the
Time Zone(hour) and Time Zone(minute) options in Easy Edit – Advanced Items/VoIP/Extensions/DT800
DT700 Setup/DT800 DT700 Terminal Settings (PRG15-05-41/42).
The default hour setting is 12, this means 0 hours offset (equal to the system).
The default minute setting is 60, this means 0 minutes offset (equal to the system).
Possible entries are 0 to 24 hours (-12 to +12 hours) and 0 to 120 minutes (-60 to +60 minutes.
Unicast Paging
There is a choice between IP Multicast, Unicast or Automatic on a per extension basis.
This is of benefit when the DT800/DT700 extensions reside on a remote network where the routers do not
support IP Multicast relay.
In the above example all extensions have the Paging Mode set to Automatic.
The system will reference the Subnet of the GPZ-IPLE and the Subnet of the extensions in the Paging
Group.
If they belong to the same network then IP Multicast will be used. If they are in different networks then
Unicast will be used and the router does not need to support Multicast relay.
SV9100 Programming
