The SV9100 supports NAT for Standard SIP Terminals.

Default Setting

SV9100 Networking Manual

IP Single Line Telephone (SIP)

When PRG 10-33-05 NAT mode for SIP phone is set to 1 (Enable), the P2P mode

for SIP Phone becomes always Off, regardless of PRG 15-05-50 setting.

Standard SIP Video call feature which uses P2P mode cannot be established in the

same system, since the P2P mode is disabled by enabling PRG 10-33-05.

When connecting multiple SIP Phones via NAT, PRG 15-05-18 has to be set to

admit registration of multiple SIP Phones which are using the same IP address. For

example, if you had a STD SIP Terminal that had two lines registering with the same

IP Address, you would need to flag PRG 15-05-18 for both Extension numbers.

In the router/firewall that the SV9100 resides behind port forwarding is required.

Port forwarding at the SIP Terminal end is not required as long as PRG 15-05-45

(Plug and Play) is enabled. The ports that must be forwarded to the SV9100 are as

UDP Port 5070 MUST be forwarded to the IP Address assigned in PRG 10-12-09.

UDP Ports 10020 ~10083, UDP Ports 10020~10147 and UDP Ports 10020~10275

(GPZ-IPLE) MUST be forwarded to the IP Address(s) assigned in PRG 84-26-01.

When PRG 15-05-45 is set to "1" the manual table setting for port forwarding may

not be required on the remote side router, but the router must support the NAT

function itself. If PRG 15-05-45 is set to "0" port forwarding at the Remote side

router is required. This feature requires the installation of GPZ-IPLE.
