Administrator's Guide for SIP-T2 Series/T19(P) E2/T4 Series/CP860 IP Phones
The following advices you need to know when using the IP phones in the wireless
network:
a) Check whether the wireless network is normal when the account registers failed or
sometimes there is no sound during an active call.
b) Ensure that the bandwidth of your wireless network is able to provide stable and
real-time data transmission otherwise the quality of video calls may be affected.
We recommend you to use the wired network for video calls.
c) For SIP VP-T49G IP phones, no matter which network (wired network or wireless
network) you are using, please properly consider whether to configure the uplink
and downlink bandwidths according to your bandwidth capacity.
d) We recommend you do not use the unstable router product in your home/office
environment.
e) We recommend you to set the password for the wireless network so as to ensure
the network resource will not be occupied by the unknown user.
