MOH not working CME 9.5 for PSTN

[dblumberg_butler_cco]

Have the following configuration:

Cisco 2921 Router with SRE-710 running CME 9.5

No calls are working when using the MOH file that we had been using on a 2821 with CME 8.6 with no problems

Have following commands in place

voice-port 0/0/0:23
 local-alerting
 timeouts interdigit 3
 !
 !
 !
!
ccm-manager music-on-hold

telephony-service

moh "flash0:/butler5.au"
 multicast moh 239.1.1.1 port 16384 

phones have multicast moh enabled and default code for ephone is g722-64

Is it possible this is getting tied up by my switches (Cisco 2960S)?

All calls are getting tone on hold.

Hi,

Check answer in this post, might be of help.

hi

kindly find the below:-

1-multicast moh 239.1.1.1 port 16384 route x.x.x.x y.y.y.y  where x.x.x.x the ip address of a loopback address and y.y.y.y the ip address of your voice vlan ip address.

2- can you test the MOH internally between two internal extensions .

3-Add the following under telephony-service

multicast-moh

4-Test without  " . use the below

moh flash0:butler5.au

5- yes , 2960 support IGMP and it is enabled by default.

6- Final thing , you have to do it , if nothing work from above. enable ip pim dense-mode under voice vlan interface and loopback

Thanks

Here is telephony service:

moh flash0:butler5.au
multicast moh 239.1.1.1 port 16384  route 192.168.117.1  172.20.10.1

One thing I forgot to mention is that MOH works fine when call is parked but not when put on hold.  

Thank you

hello

1)can you add the below:-

router(config)#ip multticast-routing

and enable  ip pim sparse-dense mode instead of dense mode under voice and loopback interface.

Thanks

please rate all useful information

[dblumberg_butler_cco]

ip multicast-routing was already enabled

The sparse-dense mode did not work

I have attached the primary config. thank you again

[yahsiel2004]

+5 Islam for the good information.

I just want to add a few things.

1 - You need to type the following command "ccm-manager music-on-hold"

2 - You don't need to turn on "ip multicast-routing" and definitely don't turn on "ip pim dense-mode". If you wanted to use "pim" use "sparse-mode". The reason you don't need to turn on "ip-multicast" is because you are already routing the traffic to the specific networks "multicast moh 239.1.1.1 port 16384  route 192.168.117.1  172.20.10.1"

3 - Also do a"show ip mroute" to make sure that you're using the correct "IP multicast address'. Remember that Cisoc IOS routers MOH only uses G711ulaw.

Here is ip mroute info

[yahsiel2004]

That's my bad, I meant to say run a "show ip mroute" while you are on hold and only if you kept the "ip multicast-routing" on. As a side note, try changing the codec on your phone to G711ulaw and place a call between the phones, to verify that MOH is working. If it's not working make sure that the location of the MOH file is correct.

Yosh

I thought that MOH is not used when internal phones are placed on hold, commands with phone on hold:

Outgoing interface flags: H - Hardware switched, A - Assert winner
 Timers: Uptime/Expires

The solution was that the G722-64 codec needed to be added to the dsp farm.  Make sure you shutdown the dspfarm first to add the codec.  Thank you again for all your help.

hi

1-+5 for yosh as usual for his great explanation. I need to add something for multicast-routing we use this command to allow transfer multicast packets between routers , l3 devices  , host (source) to send packets to a group of hosts (receivers) anywhere within the IP network by using a special form of IP address called the IP multicast group address and to allow pim protocol work properly  under interfaces. As you mentioned if i define a static multicast and define source , group and we have only one cme , ip multicast-routing enable or disable won't affect .

2-can you replace ccm-manager music-on-hold  to ccm-manager music-on-hold bind "voice vlan interface"

3- do "debug ccm-manager music-on-hold" and catch logs

Thanks

Can you share with us 

router#show ccm-manager music-on-hold

[dblumberg_butler_cco]

So I have gotten internal moh calls working using an moh-group.  I still do not have pstn calls working and just get tone on-hold for the pstn calls. When on hold I do not get any logs from ccm-manager and current active multicast sessions are 0.
