Hi I have SIP T22 Phone

Version

Firmware Version 7.72.0.30
Hardware Version 5.0.0.55

How can I enable RTCP ?

Hi Garudaz,

Do you mean that you want to use RTCP-XR feature?
If yes, you have to upgrade T22 to V73 firmware, it's supported in V73.
V73 firmware:http://forum.yealink.com/forum/announcements.php?aid=8

If not, can you explain more?

Regards,
James

Hi James,

Thanks for your response.

During an established call, I'm getting RTCP packet from the yealink phone,
but the phone is not accepting RTCP packets sent from other end, failing with port unreachable

So I would like to know, if the phone supports QoS feature based on RTCP feedback provided by other endpoint ?

Thanks
