[cisco-voip] CCM6 MOH

[Melvin Fong]

Our trouble is ending up a multicast issue, we disabled multicast and
everything seems to be working properly.

We're now going to investigate the multi cast issue

I see several possible issues related to placing SIP endpoints on hold
and then IPVMSAPP stopping streaming, but nothing obviously systemic.
Looks like IPVMSApp traces and a TAC case are next step.

OK, when I am on hold, I am getting packets... they are just blank,
apparently...

	Well the first part of troubleshooting one-way or no-way audio
is to

receiving
  

	packets and thus not have a routing issue only there is nothing
but
	    

silence
  

	in the audio packets you are receiving.  It's an important
	    

differentiation
  

	but I'd guess either way your IPVMSA is doing something funky.

	One way audio I would troubleshoot as a routing issue...
However, MOH
	    

does,
  

	in fact, work for a few seconds... and if you get put on hold in
that
	window, you hear music indefinitely.
	 
	However, if you are put on hold after that 5 seconds, you hear
	    

nothing.... I
  

	have even tried this with the same call... reset IPVMSA, get
MOH,
	    

after a
  

	minute, resume and place on hold again, and they get dead air...
	 
	This is really strange, and the IPVMSA service is still running.

		We are having the similar issue, using 6.01a, it changes
and will
		      

work
  

		one time, then when you change the MOH source it won't
work on the
		gateway but work between extensions and vis versa.

		So, I just deployed a CCM 6.01a cluster and MOH does not
work...
		      

well
  

		it sort of does...
		 
		If you put people on hold, you get dead air... if you
reset the IP
		Voice Media Streaming App, and put someone on hold
within 5 seconds,
		they get MOH, resume the call after 5 seconds (or put
someone on
		      

hold
  

		more than 5 seconds after you have reset it), and they
get dead air
		      

	again..
	    

		Any ideas? Bug?
