SmartLink 4050 Series Getting Started Guide 6 • Troubleshooting
The WAN port of my
SL4050 (PhoneB) is
connected with the LAN
port of another SL4050
(PhoneA). And, my
SL4050 (PhoneB)
become malfunction on
the networking so that I
can not get the VoIP ser-
vices. How can I do to
fix it?
To solve this problem, please change the IP segment of the PhoneA LAN port other
than the “192.168.15.xxx” first (for example, “192.168.10.xxx”).
Then, the PhoneB will automatically start to get the VoIP connection and the associ-
ated VoIP services.
It is because that in the factory default settings the SL4050 has an integrated
DHCP server to assign the IP address of the LAN port with the IP segment of
“192.168.15.xxx”.
That is, for this kind of connection of PhoneA & PhoneB (the WAN port of PhoneB
is connected with the LAN port of PhoneA), the WAN port & the LAN port of
PhoneB will be in the same IP segment (192.168.15.xxx), which will get the sys-
tem of PhoneB confused so as to be malfunction on the networking. From above,
that is the reason why we should change the IP segment of the PhoneA LAN port.
