Yealink SIP-T48G/T46G/T42G/T41P/T40P/T29G/T27P/T23P/T23G/T21(P) E2/T19(P) E2 IP
phones support two Ethernet ports: Internet port and PC port. The CP860 IP phones have
Internet port only. Three optional methods of transmission configuration for IP phone
Internet or PC Ethernet ports:
 Auto-negotiate
 Half-duplex
 Full-duplex
Auto-negotiate is configured for both Internet and PC ports on the IP phone by default.
Auto-negotiate
Auto-negotiate means that two connected devices choose common transmission
parameters (e.g., speed and duplex mode) to transmit voice or data over Ethernet. This
process entails devices first sharing transmission capabilities and then selecting the
highest performance transmission mode supported by both. You can configure the
Internet port and PC port on the IP phone to automatically negotiate during the
transmission.
