1. What's the firmware are you using? The 3CX Version of the firmware (sorry, I forgot to mention except in passing that it is being used on a 3CX phone system) X.70.0.103 depending on the model of phone.

2. So the problem is when T26P talk with T28P，sometimes there will be "dudu" tone during the call? And this tone will lasts the whole call? Or just happen one time during a call? The tone lasts the whole call until you hang up. If you put the call on hold and pick it back up, the tone persists.

Is it possible to provide us the recording of this tone？ Yes, I have it attached to the thread now.

3. What about if Yealink phone talk with other brand phones? This issue will also happen on Yealink phone side? We have had the issue happen with outside calls and internal calls from Yealink to another Yealkink.

4. Could you provide PCAP trace(or wireshark 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. I will try to get you this in the next day or two when the problem occurs again and I have time to set this up.

Thanks.
