Dynamic Or Static Setup Remote End

Dynamic or Static Setup Remote End

▐  DT700 NAPT - Dynamic NAT

l  Set the handset to DHCP in Network Settings. This should give an IP Address, Subnet Mask and Default Gateway to the DT700.

l  Be aware, when using NAT the handset does not use the normal SIP Server Settings. There is a new area for NAT addresses.

l  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 SV8100 (PRG10-12-07, 82.83.84.85).
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.

l  Exit and save, the handset will now try and register to the SV8100.

l  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.

▐  DT700 NAPT – Static NAT

l  The handset should have a static IP address or if using DHCP then reserve an address using its MAC address.

l  Be aware, when using NAT the handset does not use the normal SIP Server settings. There is a new area for NAT addresses.

l  Set IP address, subnet mask and default gateway as usual in Network Settings.
In SIP Settings/NAT Traversal/NAT Traversal mode - set to Static
In SIP Settings/NAT Traversal/WAN Settings/WAN Mate IP Address - Enter the public IP address of the SV8100 (PRG10-12-07, 82.83.84.85).
In SIP Settings/NAT Traversal/WAN Settings/WAN Mate Port - Set to 5080.
In SIP Settings/NAT Traversal/WAN Settings/WAN Self IP Address - Enter the public IP address of the router on the network where the handset belongs (82.83.84.86)

l  Port forwarding handset side
On the router connected to the handset network forward port UDP/5060 to the IP address of the handset. Also forward port UDP/3462 to the IP address of the handset.

l  If you have multiple NAT handsets on the same remote network you will need to change the port numbers on each handset so that they are unique on the network. The first handset will be ok with default port numbers.
You can change the port numbers in Network Settings/Advanced Settings/Self Port Settings - The RTP ports must be an even number, recommend 3464, 3466 etc. The relevant port forwarding will then be required.
