Hello There,
I'm having the below audio issue and would really appreciate any help
Caller =======Carrier========FS SBC======IVR
When i took a packet capture on the FS, I could observe that the audio stream quality from IVR to SBC is really
good when compared to the audio quality stream between the SBC and the caller.
Bad quality => first syllable of certain words lost, choppy ...
Using PCMU 8K on both legs ...
Between SBC and IVR - Max Delta is 96ms, max jitter is 22.5
Between sbc and caller - max delta is 120 and max jitter is 9.5
Any suggestion or help would be greatly appreciated
Regards
A

I don’t think anyone can be sure of what is causing the issue. But you can make some effort to isolate it; does this happen with all callers? Does all your origination come from the same place (e.g. carrier)? Can you test a different origination provider and see if you get the same issue?
That’s a good way to figure out if it seems to be related to the system itself or to the network path to the caller.
