voice loopback - echo - spectrum - 06-03-2015 03:43 PM Dear all, i am using a wonderful SIP-T28P, generally with my company VPN. VPN works great, only issue actually is that sometime, while talking, or when i set mute and remove mute, i start suddenly to hear my voice in the speaker, delayed of abt 3 / 500 msecs. I have already read some thread related to this, still nothing good. If some help, it's very appreciated. Best regards Angelo RE: voice loopback - echo - Flora_Yealink - 06-03-2015 05:28 PM Hi Angelo , Do you mean the scenario is like below, T28 using openvpn feature T28 are in a call with another party B T28 using speaker , during talking or when press Mute /unmute , you can hear your own voice after 0.006mseconds, for example you say " hi " then after 0.006mseconds , you can hear your own voice "hi" again ? Please help check below information : 1) if you using the handset instead of the speaker, can you hear the echo again ? 2) if another party B mute himself, then T28 press Mute /ummute again , will the issue still exist ? 3) How often the issue happen ? every single call ? 4) please help check whether you have used the latest version , it is 2.73.0.50 , if not , please help upgrade to the 50 version to see if it can fix the issue.
