Scott1234 Posted May 6 Report Share Posted May 6 Any one know if the app has a jitter buffer like a desk phone? I don't recall the app being so bad, but I am trying to use it more and notice its very susceptible to getting audio glitches all most like its running with 0 buffer, and I cant find any obvious network problems. I don't get the same when using Bria Enterprise. What else could I look at to tune it more? Generally the PCAP's look clean but the experience heard (inbound) at the app says otherwise. It sounds like I should see bad PCAPS but I don't and feel its happening at the app level. My network is rock solid and wifi on or off still the same. Bria is fine, using the user portal is fine, just the mobile app. ¯\_(ツ)_/¯ I have a group setup that just plays MOH which is an an audio book and sit in there to hear the book, I do have external DID's on it as well for external testing but its on all levels. 1.22 (65) 68.0.30 Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted May 10 Report Share Posted May 10 Yes there is a jitter buffer. Most of the quality issues are because G711 sounds very bad when there is packet loss. In environments where there is no packet loss, G711 sounds best, simple because transcoding can never make audio sound better (unless there is some AI magic at play). But if there is packet loss, OPUS behaves dramatically better. So in a nutshell, if you have packet loss on the app, set the extension to OPUS.

Scott1234 Posted May 12 Author Report Share Posted May 12 I will give OPUS an experiment I have not spent any time with it yet. Like I said the network is good, should be no packet loss, and PCAP's look clean. I usually find the issue is at the start at call setup the first 2 seconds then its fine. Both sides normally hear glitchy bad audio then goes good. I some times hold off saying hello for a second as I know its better that way or I get the comment 'this sounds like a bad line' ... lol. Maybe play more ring back locally to allow better establishment ? This also happens dialling into a attendant playing an audio book, so eliminating any carrier issue, 3 hops to pbx sub 5ms, zero loss. Maybe its a TLS thing Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted May 16 Report Share Posted May 16 ... on a side note, we have introduced a setting for mobile client codecs in 69, so that a desktop phone can be on G711 and the mobile device on OPUS. Its all optional, but in most cases this makes sense. Quote Link to comment Share on other sites More sharing options...
Scott1234 Posted June 3 Author Report Share Posted June 3 I tired OPUS only and still the same the first few seconds of connected call on the app are broken / jittered then smooths out, every time. 711A/U or Opus. Wi-Fi or LTE same. Bria Enterprise seems to be fine with the same tests. Confirmed with pcap that OPUS was being used. Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted Monday at 06:25 PM Report Share Posted Monday at 06:25 PM It might be because Bria does not use DTLS (SDES), in other words not end-to-end encrypted. You can see the keys in the SIP messages with SDES, which is becoming kind-of not-okay. Quote Link to comment Share on other sites More sharing options...

Apparently, something to do with this , RFC 5746 - Transport Layer Security (TLS) Renegotiation Indication Extension (ietf.org) Quote Link to comment Share on other sites More sharing options...
