When I adjusted playback-volume and record-volume the rsult was bette voice quality, so the problem was not in queues.

What is the difference between playback-volume and record-volume parameters ?

The PBX's are Panasonic KDX-100, but MT there is no options for my region in Bulgaria.
I will try the voice quality w/o queues.

I use external line from PBX, so it is the same as telephone.

For example:
Call from A TO E:
PBX-PhoneJack-MT-FrameRelay - MPLS Core Network - Ethernet-MT-Voicetronix-PBX

Yes.
I have to use queues, because I have voice and data.
How quality is going to improve If I disable queues ?

I have five routers as follows: A. 64 kbps - Frame Relay - PhoneJack - PBX B. 64 kbps - Frame Relay - PhoneJack - PBX C. 64 kbps - Frame Relay - PhoneJack - PBX D. 64 kbps - Frame Relay - PhoneJack - PBX E. 512 kbps - Ethernet - Voicetronix - PBX During conversation from all of them I have interrupt...

Yes I know, but this sniffer do not give information about TOS field in packet

I would like to If MiktoTik has tool which I can use to sniff the outgoing packets?
I want to see with what kind of TOS field previosly mandled flow leave from outgoing interface or come to outgoing interface.

Thank you. I have Tigerjet phonejack voice card. When I make mangle rule in order to mark voice traffic which come from voice card.

Now I understood. Thank you.
I plan to preoritize voice traffic over data. Would you suggested me good solution about queuing mechanism ?

Thanks.
What about if I change the order of the mangle rules ?

[kpetkov@KK-Varna] ip firewall mangle> print Flags: X - disabled, I - invalid, D - dynamic 0 src-address=192.168.1.0/24 dst-address=192.168.0.0/20 action=passthrough mark-flow=data set-tos=224 1 dst-address=192.168.0.0/20 action=passthrough mark-flow=voice set-tos=96 [kpetkov@KK-Varna] ip firewall m...

Unfortunately router mangle only data traffic with TOS=224, voice traffic remain TOS=0. Is there someone who meet with th...
