VP530 Bad Sound

[Yealink Support]

The problem we have is with the audio quality for the first few seconds of the call. The problem does not occur on any of the T26's or T28's in the same office, only the VP530's. I brought one back to my office for testing and had the same experience. We had our vendor replace the device and the new one is no better. I've tried several codecs and it seems to have the lease impact on 722 but is still noticeable.

My question (I'm not here only to rant) is: Can we adjust the jitter buffer on this phone some how? On the other Yealink phones it's under audio but I cannot locate it on this model (firmware .10 or .40) and wonder if it may help.

Hi Pmterp,
1. So you mean when you make the video call between two VP530, the voice quality for the first few seconds is bad? You can't hear clearly each other?

2. Could you provide PCAP trace, syslog(level 6) and config.bin file to us, so we can analyze?
Before you export the syslog, please set log level as 6, and reboot the phone, then click Start,and reproduce the issue, then click Stop,and export the trace, syslog, config,bin to us.
(About where to export these files, please refer to attached screenshot.)
These three files are very important for us, hope you can kindly understand.

3. Could you let us know more information about this client? What kind of project?(If you think you can't public these information here, you can send to support@yealink.com)

4. And could you let us know where are you from, and where you buy the phone? So i can introduce our special technical support engineer and sales to provide you better support.
Thanks.
