Re: [cisco-voip] digitized voice quality

[Erick Bergquist]

Is part of the call going over analog or tdm circuit (pri) or dsp resources
used?

I’ve heard of digitized (robotic) voice across the above and sometimes
physical hard phones with dsp issues mostly.

What codec is in use in capture of bad call? Diagnostic CDRs aka Severely
Concealed Seconds (SCCR) shows what? How are users connected? Packetloss or
high delay usually causes poor audio. I don't like G729 as in packet loss
sounds worse, wish CUBE had OPUS (coming).

[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?

we have had multiple users say if they add Video to the call it makes it

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?

[cisco-voip] digitized voice quality

[Scott Voll]

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
