of the 802.1ptag field and the 802.1Q tag field respectively. Both are a 16-bit

unsigned integer.These metrics are sent for the first RTP packet received.

full-duplex, half-duplex or acoustic echo cancellation mode. The acoustic echo

cancellation metric is an enumerated type metric. The possible values are:

● 0 = Half-duplex

● 1 = Full-duplex

● 2 = AEC

There is no acoustic echo cancellation on the VoIP engines. Acoustic echo

cancellation is a feature for IP phones only.

can be used with the Avaya VoIP Monitoring Manager.
