Networking Manual
NAT mode for SIP Phone which can not use SIP P2P mode and standard SIP
video call feature uses P2P mode cannot establish in same system.
When PRG 10-33-05 NAT mode for SIP phone is set to 1 - Enable, P2P mode
for SIP Phone becomes always Off regardless PRG 10-26-03 setting.
With Version 4.0 or higher the system time can be provided using NTP time
server updates to standard SIP terminals.
When connecting multiple SIP Phones via NAT, PRG 15-05-18 has to be set to
admit the 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 SL1100 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, which it is by default. The ports that must be
forwarded to the SL1100 are as follows:
UDP Port 5070 MUST be forwarded to the IP Address assigned in PRG

10-12-09. UDP Ports 10020 ~ 10083 MUST be forwarded to the IP
Address assigned in PRG 84-26-01.
