Incoming audio loss - DanielG - 03-27-2018 01:06 PM

Hello,

Recently we have started getting reports of occasionally audio drops on incoming callers. I have been able to reproduce this in the lab and occasionally the audio from the outside caller will drop a word every sentence, it is very random. When inspecting the audio it is intact when leaving our system and seems to be dropping audio at the yealink level.

Any suggestions as to where to look next?

Hi,

If the phone(s) get the power by PoE, please use separate power adapters and test again.

Hope this will help.

Hello,

Thanks for that suggestion, I have tried with a power adaptor and the issue persists.

I have attached a pcap

HI DanielG ,

Do you mean the first word in every sentenses will drop? Or the first word in first sentense will drop?
Does the issue happen only in incoming call? Both the voice of two sides will drop? Or only the caller side? Or callee side? Is it internal call or external call?
How often the issue will happen?

Please provide the level 6 syslog, config.bin and PCAP when you reproduce for us to debug. Before test, please upgrade the firmware to latest version.
Refer this FAQ to collect it:

Besides, how many phones the customers have in total? ANd how many of them have the issue?

Best Regards,
Lucia
