Voice delay Yealink vs Grandstream - patbouch - 03-03-2016 10:18 PM Hi, 4 phones on the same Ethernet switch in laboratories with asterisk server. 1 x T23G 1 x T27P 1 x T21P E2 and 1 x Grandstream DP715 During a conference call between master phone (T23G), slave (mute enable, T27P) and slave (mute enable, Granstream DP715), i hear easily a delay of about 100 ms between the two slaves. I say "check", I hear in the grandstream, and after in the Yealink. I tried with the T21P E2, same result. (100ms after, time to say "check"). But T21P E2 and T27P, in slaves, they receive at the same time. Conclusion : The grandstream DP715 restores faster the sound. I reduce the Jitter Buffer (20/80/40) without success. Does the processor/firmware is slow to return the song ? I personally think it's a problem on the firmware performance. Knowing that every millisecond is important... This is not good... Last firmware : TXX-44.80.0.95 Do you have an idea of the problem? Patrick Bouchard RE: Voice delay Yealink vs Grandstream - Klaus_Yealink - 03-04-2016 06:24 AM Hi, thanks for your information.
