T41p voice delay when calling in

[johncwkamms]

T41p Phones having a issue when calling out , we receive about a 3 second delay before the person calling in is heard . They can hear the yealink T41p user/caller perfectly fine.

we have a total of 10 t41p phones installed. Only 5 out of the 10 have the delay issue. The other 5 work fine.

I'm thinking firmware . any one out there have any ideas or experienced this issue.

No, Hard to explain sorry,
Let's take this scenario ....
1-client is at her desk , picks up yealink phone and dials out (to my cell phone).
2-phone rings my cell phone or any phone outside the phone system it self. (Off premise)
3- I answer my cell phone and say hello. The person on the yealink side doesn't hear hello they miss the first 3 seconds of the call. But I can hear them the yealink phone side perfectly fine..

Hi johncwkamms,

Sorry, I explain incomplete, please upgrade to the latest firmware and reset to factory firstly in issue phone.
