Round Trip Delay on Avaya IP Office IP Trunk 1

[casdtechdir]

I have 2 buildings in my environment and each building has an Avaya IP Office Phone system. I am still using Digital and Analog Phones, but calls between the buildings are made over my IP network. I am not currently experiencing any poor call quality issues, but i keep seeing Round Trip Delay errors in my Avaya System Status under Call Quality Of Service. I am seeing these error message on both systems.I have HP Procurve Switches. The buildings are connected over a 1 gig fiber trunk. I have setup a dedicated VLAN for the 2 phone systems. In my HP core switch I designated the VLAN as a "voice" vlan. I have also enabled QOS and gave the VLAN priority 7 on the network and also added DSCP 46 to the VLAN. This was per my avaya vendor and I also found it when looking for Avaya IP Office with HP Procurve switches.Any suggestions on how to correct this so that the errors go away. I believe i already moved the alarm threshold to the highest it could go as the alarms were set the the default levels and may have been to sensitive.

Don't trust system status for IP quality stuff. It'll tell you that there's 99.9% packet loss on perfectly good calls too.

* For Kyle for restating what should be common knowledge for all IP Office maintainers.

My advice to end users who start reporting this type of thing is "don't go looking for trouble, you will know about it soon enough if you do have a problem"
