[cisco-voip] digitized voice quality

[Pawlowski, Adam]

That and what the regional bandwidth/codec lists are set to

Perhaps some calls are using g729 or something which would sound pretty gross on a PC headset in comparison to opus or even g711

Who is hearing the poor audio, the jabber user?  the person the jabber user is speaking to?  is this jabber to jabber only?  is this over wlan or lan?

One idea for why audio sucks but audio+video doesn't is that your priority queue is dropping packets and when video is added both audio and video are af41 and therefore circumvents the priority queue.

Can you confirm the dscp values on the voice stream for a voice only versus voice+video call?

All--

we are using Jabber 12.8 with CM 12.5 in a voice only mode.  we have users reporting digitized voice call quality.  has anyone else been dealing with this?

we have had multiple users say if they add Video to the call it makes it better.  Anyone else seeing that?  Any ideas why that would be better?

what else can we do to make this work better?  TAC has not been able to help with this after multiple weeks of engagement.

any thoughts?

TIA

Scott
