VoIP Trunks Dropping 1

[searay2005]

We have two BCM200's that have cumulative patches and are connected by VoIP trunks over the Internet.

Everything works but anywhere between 6 minutes and 18 minutes into the call the connection is dropped.

Watching on BCM monitor if one user hangs up the phone the call is ended by two lines on the MCDN page both saying Disconnect Normal, but if the call is dropped there is only one line that says Disconnect Normal.

Is there a timer in the system that will drop the call, or is there another patch for dropped calls, or are we dealing with a router / Internet problem?

The bandwidth for each VoIP call is only 23K.

have you installed the latest FEPS and CORE patches? the version within the cumulative patch are already outdated.

calls can also be dropped with cause "normal" when no packets are delivered for a period of time. bad line or too much traffic on that line.

Thanks Steeef,
Do you have the file names of the patches or have a link for the patches?
I will apply the patches but we do suspect the high-speed connection and lost packets.

A good tool to test and monitor connections is "NetIQ VoIP Assessor". It will simulate VoIP calls and show statistics about the connection. Jitter, delay, lost packets and much more.

You can find the patches on

http://www.ftp.etkn.de

Just type "searay" into the textbox to gain access to the files. Since i dont know what version your BCMs are i put CORE and FEPS patches for both versions here.

Thanks Stefan

I will apply the patches and I have downloaded the demo of the assessor.

I also have a call into NetIQ to get a temporary activation.

Can you run the tool remotely or do you have to be at one of the customers sites to use this tool?

Since this tool is simulating calls between two endpoints, you have to install the software on a pc on one end and a small endpoint software on the other end. The endpoint can be downloaded here:
