I have a 2820VN that was running 3.3.3. I edited the bandwidth management config to reflect the fact that I have a SIP device at home.
I configured the following service types...
1 SIP TCP/UDP 5060
2 SIP Tunnel TCP 5090
3 RTP UDP 16384-32768
4 SIP TLS TCP/UDP 5061
5 STUN TCP/UDP 10000
I then configured the rules...
NO Status Local Address Remote Address DiffServ CodePoint Service Type
1 Active Any Any ANY SIP
2 Active Any Any ANY SIP Tunnel
3 Active 10.1.0.22 Any ANY RTP
4 Active Any Any ANY SIP TLS
5 Active Any Any ANY STUN
Where 10.1.0.22 is the address of the device...and I applied these to the class 1 traffic
Then on my general index I set the following...
WAN1 General Setup
Enable the QoS Control
Index Class Name Reserved_bandwidth Ratio
Class 1 SIP VOIP 70%
Class 2 10%
Class 3 10%
Others 10%
So in theory when any SIP traffic is present is should get the higher ratio of the bandwidth. On checking the online status we could see the SIP traffic - no issues.
I then noticed that during iTunes updates my voice was becoming 'droppy'. I checked with a colleague and we removed the STUN config.
Since then all traffic is shown in the 'others' class and voice is droppy despite the fact that QoS is enabled. I upgraded to 3.3.4 (before I read the forum) and we had no difference...once I read the notes I downgraded to 3.3.3 a - this did not seem to resolve the issues so I did a 3.3.3 rst....still now joy.
Others have reverted back and all seems to have been cleared but this does not work for me.
Anyone have any ideas?
