3CX Firewall Checker Client Application

[herbst]

Hi,

We have poor call quality, and checking our ISP.

We try use Remote firewall/Nat test utility.
Is it possible test, how audio packets lost?

Calling *777
Connection with *777 established
Audio port is 7090
Echo call - 2876 packets received

What is mean last record? is it ok?

Hi @herbst ,

Do you have call quality issues only with external calls or internal as well?
Also does this happen on different phones or is this a specific phone?
For troubleshooting i would suggest that instead of using the 3CX Firewall Checker Client Application, try getting a wireshark capture on the PBX while you replicate the issue. Then listen to the different audio streams so you can determine where the audio problem is originating from. (Provider->PBX? PBX->Phone? Phone->PBX? PBX->Provider? )

Hi,

We have 3 ISP in test. all is ok via one (3G), but we can not use them in production.

I should select from two 4G. Wireshark is ok for get technical data, but I was hoping to get the result faster and easier with the help of 3CX Firewall Checker Client Application utility. Like Ping Utility.

thx in any case.
