Are these the counters to identify voice mute in VoLTE (Nokia Vendor)?
For Nokia probe data can help.
Do you mean from Drive Test?
I mean from Core side we have probe capturing data related to mute call.
Annova tool.
L.Voice.UL.Silent.Num & L.Voice.DL.Silent.Num.
These counters are available in Huawei
//Number of times that a UE experiences uplink or Downlink voice mute in the cell
You could use the VoLTE Break KPI’s/Counters:
LTE_6242b {M8067C0,M8067C1,M8067C10,M8067C2,M8067C3,M8067C4,M8067C5,M8067C6,M8067C7,M8067C8,M8067C9}
LTE_6243a
M8067C11,M8067C12,M8067C13,M8067C14,M8067C15,M8067C16,M8067C17,M8067C18,M8067C19,M8067C20,M8067C21
Each Bin will be an indication of Silence/Mute duration.
Thank you.I will check and come back
Can u share ericssion counter
Hello Experts.
Do you know how can we detect fake and mute call in 5G, with KPI?
Vendor is Huawei and Nokia.
mostly CCE Allocation Failure is the main cause for silent calls, check the related counter of CCE Allocation Failure
Check RTT value, it should be as per design.
RTT is round trip time delay between enb and antenna. Login to bts manager and under parameters you can find it. I used RTT value 20. If this value is not as per design, call muting problem comes.

how can i troubleshoot silent calls using U2020 for nodeB?
This is a very general question, and there’s no magic solution.
You need to check your vendor counters (as you’re mentioning U2020 I assume you’re talking about silent calls in Huawei), the counter related to this issue.
You need to check RAT (GSM, WCDMA, LTE?). As you said “nodeB” i assume it is for 3G.
In short, there are a lot of thing to do, but you need to first let your scenario clear. For example, how did you identify silent calls?
Customers experience the silent calls and made the complaints
All the major KPIs are fine(Accessibility, Mobility, Retainability). No packet loss.
Did you check these counters suggest here? 
Also, did you check the replies to that post - doing same verifications suggested (as possible degradation cause?)
Those counters were for VOLTE
Sorry, i don’t know counters for Huawei 3G silent calls.
Others can suggest.
What happens if the algorithm is in the invalid state for a huawei network, what is gained by putting it in active mode and in the case that I have to, it would be failing to win.
