The cable connection is correct, the speaker system is operating properly, but there is no audio output at the local site.
Step 1 Telnet to the center telepresence codec.
Step 2 Run the bsp setprivateip ? command to query how to configure the PoE port's IP address for the telepresence codec.
main cpu-> bsp setprivateip ?
setprivateip 184.108.40.206 255.255.255.0
ip must be C class address
and last number must be 67(x.x.x.67)
netmask must be 255.255.255.0
Step 3 Run the bsp setprivateip 220.127.116.11 255.255.255.0 command to set the IP address.
The static IP address of the telepresence host PoE port is 18.104.22.168. The IP address and subnet mask of the telepresence codec's PoE port must be set to 22.214.171.124 and 255.255.255.0.
The telepresence host's Power over Ethernet (PoE) port is assigned with a static IP address 126.96.36.199, but the telepresence codec's PoE port is assigned with a dynamic IP address using DHCP, causing IP address mismatch.
