What do hear when you believe it suddently stops ToH or Silence?

Verifiy that multicast active resources counters increment from with perfmon or RTMT, depending on how you have implemented your MoH server within CallManager.

If you see that the appropriate counters are incrementing then you can be assured that when IP phone is on-hold that CCM is providing the audio-source.

The next aspect is to verify whether the IP Phone is receiving the multicast audio stream. Put a sniffer on the back of the pc port to verify this, if there are no RTP packets on-hold then problem could reside with your network, specifically your multicast routing and where you have deployed your RPs.

How long has it been running like this? Is it only recently this has started? If this is the case are you aware of any changes within CCM such as ES updates, or changes in the underlying network regarding multicast?

Hi Gokhan,

If no objections, you may upgrade to latest SR in 4.1(3). SR6 will be posted soon now we have sr5d.

That includes several fixes for IPVMS problems.

Or checked what previous posts indicated and open a case with us to find out what exactly is happening at MRM level.
