Hello:
I have installed a CCME voice network, I use 7940 IP Telephone and ATAs. The equipments are connected to a Switch Cisco 3550, have power on line feature and IP Phones are configured to 100 Mbps full duplex. Some users have quality voice problems.
What is the minimum cable category that cisco suggest to voice?
Is the speaker mode full duplex or half duplex?, may be this can be the problem.
Is there a way to priorize traffic voice into the switch, the connection is shared between PC an phone?
regards
