We've been receiving traps for "Poor Quality of Voice" for sporadic calls from several of sites across our VoIP network. If I'm understanding what I'm reading, the trap is being sent when CvVoipCallHistoryIcpif is too high.
I'm trying to figure out what is causing the ICPIF value to get where it is at (59 or 66 depending on the codec). One-way transmission time is listed as one of the values used in the calculation. Is there a way to see what the one-way times are for a given call? I know that RoundTripDelay is listed in the call history, but wasn't sure if it affected the ICPIF value directly or if another measurement was used.
It was my initial thought that RoundTripDelay was the trigger, since I've seen times upwards of 32000ms, but in these cases, the value of CvVoipCallHistoryIcpif is sometimes 59/66 and other times zero.
Packet loss doesn't seem to be an issue either. Is there a specific value I can look at to see what "one-way tranmission time" is being used for ICPIF?
