In our DL set up - we have two SX80 codecs connecting with a WebEx Plus codec. We are generally connected Monday through Friday from 8 am to 5 pm. However, in the past few weeks we have video glitching at the site with the WebEx Plus codec and then it disconnects from the system and locks up the interface for our two SX80's. We generally have to disconnect, reboot all the codecs and re connect. But this is seriously hampering our educational efforts for our students. We are connecting via SIP to make all three rooms work. Any suggestions?
Please provide more information about your environment.
These codecs - what are they registered to - CUCM, VCS, Webex? What software version are they? Your initial description implies you are using Multisite on the the plus with the two SX80's connecting to it, but later you state that the plus disconnects from "the system" - what system? CMS, Webex, a legacy MCU?
Sorry for all the questions, but we need a clear picture of the problem to try to help you fix it.
Please get your firewall checked for any packet drops or ACL related to your Plus device as source IP.
From description it seems to be a firewall playing some tricks or could be bandwidth issue.
