We have had some random disconnects with several of our HDX 8000 & 9000's and can't seem to find a common thread. All conferences are run through an RMX 2000 with multiple endpoints. All on a healthy internal network.
When looking at the CDR's, it just says "Call Disconnection Cause: h323_call_closed_normal ". I don't believe end users are ending the call and I am not ending the call. Anyone else experience this or have any thoughts? TIA.
Are the sites inside/outside of your network ?
Do they disconnect if you try a Point to Point call ?
What version of code are you on ? (HDX/RMX/etc)..
Is there a Gatekeeper involved (RPRM, CMA, PN, etc) ?
Need more information to try to help..
Thanks for the reply. All calls (even P2P) are run through the RMX so I can't say for sure. I will test a few though and see. Yes we have a CMA and everything is scheduled through it as well as GK functions. As far as code versions -
RMX - 18.104.22.168
CMA - 6.2.4.ER8 - HW Rev. A
All 9002's - 22.214.171.124-38311
8000's - 126.96.36.199-38311 , 3.1.4-43132 or 3.1.5-5568
All calls are conducted internally on our network.
If you can, un register two of the systems that have been dropping... and then dial the bridge using the signalling address ## meeting room number. See if the call drops...
If it does NOT drop, then your focus needs to be on the CMA/Gatekeeper...
If it does drop, the issue gets pointed back to the network.
Are the disconnects at specific time intervals? For example, we have had problems with 20 minute disconnects and 2 hour disconnects. Each time it was because the endpoints were on a VPN link and the KeepAlive value was not set properly to prevent the disconnect from triggering. I can go into more detail if you would like.
