Exempt Networks.
Enter the network address and subnet mask of DT800/DT700 LAN terminal via local router (if connected –
see below for further information).
Port forwarding system side
On the router connected to the SV9100 network, forward port UDP/5080 and UDP/5081 to the SV9100 GPZ-
IPLE IP address.
Also forward the RTP ports (UDP/10020 - 10532) to the SV9100 VoIP gateway address. More entries may
be required depending on the configuration and if NetLink is used.
Static or Dynamic NAT
There are two options available when programming the handset, Static NAT or Dynamic NAT. The choice
depends on the capabilities of the router on the handset network. If UDP Session Detection is supported
by the router then Dynamic NAT should be possible. It is recommended, where possible, to use Dynamic
NAT.
Dynamic NAT
The router on the handset side must support dynamic address and port mapping for outgoing and
incoming traffic.
Enter the Config Menu of the handset and Enable DHCP Mode in Network Settings/DHCP Mode. This
should give an IP Address, Subnet Mask and Default Gateway to the DT800/DT700.
Be aware, when using NAT the handset does not use the normal SIP Server Settings. There is a new area
for NAT addresses.
In SIP Settings/NAT Traversal/NAT Traversal Mode - set to Dynamic
In SIP Settings/NAT Traversal/WAN Settings/WAN Mate IP Address - Enter the public IP address of the
SV9100 Easy Edit –
DT700 NAT Setup/NAPT Router IP Address.
In SIP Settings/NAT Traversal/WAN Settings/WAN Mate Port - Set to 5080.
In SIP Settings/NAT Traversal/WAN Settings/WAN Self IP Address – Leave this blank, the phone will get this
address dynamically.
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.
Static NAT
The handset should have a static IP address or if using DHCP then reserve an address using its MAC
address (if supported by the DHCP server).
Be aware, when using NAT the handset does not use the normal SIP Server settings. There is a new area
for NAT addresses.
Set IP address, subnet mask and default gateway as usual in Config Menu/Network Settings.
In SIP Settings/NAT Traversal/NAT Traversal mode - set to Static
