SIP MLT NAPT Enhancement
The Dynamic NAPT (Network Address Port Translation) feature has been enhanced to improve the
performance of SIP MLT when used with a dynamic router connected at the terminal side.
Port forwarding on terminal side should no longer be necessary when using this feature with a suitable
dynamic NAT enabled router. If using a Static NAPT router configuration then the setup details found in
SIP MLT NAPT should still be used.

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.
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 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
