IP Single Line Telephone (SIP) – NAT Mode

With SV9100 system software, the SV9100 supports the NAT (Network Address Translation) mode for

Standard SIP terminals.

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

SIP Phone becomes always Off regardless of Program 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 Program 10-33-05.

SIP Station – GPZ-IPLE does not support a Blind Transfer feature.

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

registration of multiple SIP Phones which are using the same IP address. For example, a

Standard SIP terminal that has two lines registering with the same IP Address requires

Program 15-05-18 to be set 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 Program 15-05-45 (Plug and

Play) is enabled. The ports that must be forwarded to the SV9100 are as follows:

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

UDP Ports 10020 ~ 10531 (GPZ-IPLE), MUST be forwarded to the IP Address (s) assigned in

Program 84-26-01.

When Program 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

Program 15-05-45 is set to "0" port forwarding at the Remote side router is required. This

feature requires the installation of GPZ-IPLE.
