Hi CSCO10571159,
When you you put pstn caller on hold , the mrgl, mrg of the held partyy is checked and the audio source of the phone who is pressing the hold button is checked.
1) Please check the MRGL of the gateway through which the calls are going by going to device page of the call manager
Device-->Gateway -->Select the gateway ---check the gateway has the mrgl which contains the mrg which contains moh server.
since in this case only pstn callers are the ones having the problem , so the mrgl of the held party which is pstn in this case, hence the mrgl of th gateway needs to be checked.hence the mrgl of the gateway should have the mrg which should ontain moh server.
But since you are hearing the silence or dead air I am suspecting thats not the issue with mrgl because then you would be hearing 3 beeps or tone on hold
2) are you using multicast or unicast ??
If you are using multicast, have you tried with unicast ??

Hi,
Make sure that the file you are using as the audio source on the phone who is pressing the hold button is present in all the servers the clusters.
Also try to make it work using unicast and check show call active voice brief while putting the pstn caller on hold atleast 3 times to see if the Tx.Rx packets are being incrementing.
Please Rate if you find this info useful.

Hi Vignesh,
I think you are talking about the bug CSCtl21854 but if you look at the bug details this is applicable in 15 version of IOS image , and he is running 12.4 image.
Also Please make it work with unicast , if that works with unicast, then we will troubleshoot why it is not working with multicast.

Ping just means there is connectivity, not that it's properly configured or that it should work.
Go to GW config, look at the MRGL field (and also at the device pool since there is a MRGL trere as well). At least one of those MRGL need to have the MOH server so you can get MOH.

Hi Sumit
i have a MOH issue, can you help me plz to solve it
i`m using cisco cucm-BE with mgcp protocol with the gateways,
When someone called form the pstn to the cucm and after he hear the autoattendant:
the MOH only works when i press 0 (the operator) and when i press an internal extension i hear a ring back tone and sometimes i hear the MOH for one second but when i dial 0 i hear the MOH Normally after "wait while i transfer your call"
how i can hear the MOH too after i dial the internal extension normally?
the following is done:
-am using unicast MOH
- that media resource is enabled. Media Resource->MoH Server and verify that the run flag is set to YES.
- Restart the Cisco IP Voice Media Stream App service.
- Check if G711,G729 is enabled for MoH in Service Parameters->Call Manager->Cisco IP Voice Media Stream App service.
- the IP Phones or Gateways has assigned the MRGL that include the MOH resource.
thanks

I am afraid that is not working with multicast or unicast
I check MRGL on GW.In fact RTMT counters of MoH unicast resource avaliable decrease when I press hold button for PSTN callers

Hi,
Greetings,
AFAIK, When hearing silence on pressing hold,99% of the time it is related to infrastructure, and now a days one particular command ip cef creates problem(silence). Can you try executing command "no ip cef" and test the same ?
Usually Tone on Hold means its CUCM configuration issue.
Will share more about this based on the test result.

Re bug CSCtl21854, Enabling Duplex Streaming in the CallManager service parameter fixed our issue. PSTN and external SIP calls are now hearing MoH.

Also execute the command "ccm-manager music-on-hold", this command is required for both MGCP nad H323 gw's
