Both pub and sub are sending different audio sources on the same IP  
address/port?

Thanks Ryan--

So I have both Pub and Sub sending MMoH and the 1st node on the new  
cluster.

Love it. ;-)

Since both the Pub and Sub are both sending could this just need a  
MRG reset on all devices to fix it?  then fix the new cluster and be  
done?

If it's MMOH then you can simply do a 'show ip mroute' on the gateway  
to see which stream(s) it is getting and what interfaces they are  
arriving from.  You can then follow them backwards until you can look  
at the source mac address.

You may also want to make sure there aren't any sources on the new  
cluster enabled for multicast.

And to add to it, thus wanting to find the source I'm in the middle  
of my upgrade to cm 6.1 so I also have those servers on the network.   
thus I need to make sure they are not causing it either. ;-)

I'm dealing with an issue right now of callers on hold hearing the  
same MoH sound bit, but they are hearing what seems to be two  
different streams.

they over lap but not together.  music <then womans voice saying bah  
bah> music < man saying bah bah>  but the caller hears the music then  
they hear both the man and womans voice not quit together either.

I would like to see where the two streams are currently coming from  
(one from pub and the other sub?)

CM 4.1.3sr6.

Can someone tell me from a VGW how I could see those source IP /  
ports so I can see where my issue might be?

Thanks

Scott
