When migrating to a VoIP solution, it is important to track certain key performance indicators (KPIs) to ensure the media quality is meeting the required standards. The following are the three KPIs that are used to track media quality in VoIP migrations:
A. Delay: This KPI measures the time it takes for voice packets to travel from the sender to the receiver. Delay can have a significant impact on the quality of the call, particularly if it is excessive. The delay can be caused by various factors such as network congestion, processing time, or distance.
C. Jitter: This KPI measures the variation in delay between packets. Jitter can cause problems such as distorted or garbled speech, and can also cause packet loss. High levels of jitter can be caused by network congestion, delays in processing, or variations in packet arrival time.
D. Packet Loss: This KPI measures the number of packets that are lost during transmission. Packet loss can have a significant impact on the quality of the call, causing distortion, garbled speech, and gaps in the conversation. Packet loss can be caused by network congestion, hardware failures, or inadequate bandwidth.
Trunk group usage (B), call processing (call detail records) (E), call processing (performance counters) (F), echo (G), and crosstalk (H) are not related to media quality, and therefore not relevant KPIs for this purpose.
