Hi everyone, Recently we've been experiencing some unusual audio issues on our SIP gateway (running Freeswitch) where people on a conference are sometimes hearing periodic / digitized 'beeps' or 'clicks' during the call (mainly when someone's speaking). You can listen to a recorded clip from the call at: https://www.dropbox.com/s/aya3j8xkxtz0wx6/AudioSampleBeep.mp3 The caller was coming in via a landline through one of our carriers. Our FS server wasn't under any particular strain for resources at the time nor does it seem too widespread (it happens pretty non-deterministic from what I can tell) but thought I'd share in case anyone has heard anything similar in the past and if there are insights worth sharing on this. Any feedback would be awesome, Imran
