Hi every one,
I have call manger 5 and alot of CISCO IP Phones. All phones work fine by Power over Ethernet PoE
Now, we have a office that is far from the main buliding about 185 m, I making LAN cable from Switch to Phone (about 190 m cable)
when tried to connect the CISCO IP Phone 7911, it gave "configuring IP" and after that gave "Disconnect ethernet"
Can any one tell me what is the problem ? and What is his suggestion to solve this ?
