HDX's Disconnecting

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.

Re: HDX's Disconnecting

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..

 

Cheers,

Re: HDX's Disconnecting

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 - 7.8.0.246

CMA - 6.2.4.ER8 - HW Rev. A

All 9002's - 3.1.3.2-38311

8000's - 3.1.3.2-38311 , 3.1.4-43132 or 3.1.5-5568

 

All calls are conducted internally on our network.

Re: HDX's Disconnecting

Dave,

 

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.

Re: HDX's Disconnecting

Dave,

 

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.

 

Thanks,

 

Tom
