voice delay Yealink vs Grandstream

[patbouch]

Hi, i change network port, (T27P <--> Granstream DP715), no change.

Thanks for you help.

Also,

T23G master
T27P or T21P E2 slave (mute enable), same result. I hear with about 100 ms of delay (after) compared to the Grandstream DP715.

If I would not have had the Grandstream to compare, I would have thought the time was normal. But now I'm not sure.
