2. Setting port forwarding on the router
To ensure that your specified SIP and RTP port numbers are used on the WAN interface
with the public IP address, you must define port forwarding rules for the SIP and RTP ports
on the router.
To define port forwarding on the router, proceed as follows:
The terms used below may vary from router to router.
To release a port, you must enter the following details (example):
Protocol
Enter
UDP
as the protocol to be used.
Public port
Port number/port number range on the WAN interface.
Local port
The SIP and RTP port numbers set on the phone.
You can set an RTP base port for the Gigaset N720 DECT IP Multicell System base
stations, from which the system automatically determines the ports required (32 per
DECT module) (
). You must then also define corresponding port
forwarding for this range.
Local host (IP)
Local IP address of your phone in the LAN. The phone's current IP address is displayed
on the router.
To enable the router to perform this port forwarding, the DHCP settings of the router
must ensure that the phone is always assigned the same local IP address, i.e., the DHCP
does not change the IP address assigned to the phone during operation. Alternatively,
you can assign a fixed (static) ID address to the phone. However, you must ensure that this
IP address is not within the address range reserved for DHCP and is not assigned to any
other LAN subscriber.
