When I try to transfer a call, Blind, Semi-Attended, or Attended, the recipient only hears silence.

Has anyone else had this issued?

Thanks.

Dear,

This is Kevin from Yealink tech support team, nice to know you here.
About this case, please tell me how you do transfer call:
1. A call B, and B answer; then B press TRAN to do transfer call to C. If C answer this call, C can't talk with A, right?
2. If A direct call C, or B direct call C, may I know if the audio is good?
3. Can you tell me your FW and model?
4. Can you use IP direct call to test this scenario?
5. May I know how many phones in your side and how many phones are affected by this issue?
6. Can you reproduce this issue again, and send me PCAP, syslog(level 6), config.bin files to me? For how to export those files, please refer to this FAQ:

Please help check and let me know.

Best Regards,

Hello, Kevin -

1. Correct.

2. Internal calls have good audio. Direct external calls have good audio.

3. What is FW? Phone model is T23G.

4. I do not know how to use IP direct call to test this scenario.

5. We have 7 phones. All phones are affected.

6. I can reproduce this issue consistently, but the export directions provide do not work, so I cannot provide the requested files at this time.

Thank you.
