Lab 1 / Task 6.X : MOH multicast issue
Hello,
NB : For my studies, I use 4 CIPC softphones (HQ/BR1/BR2/PSTN) running on my laptop (using virtual machines and Cisco VPN client to connect to the rack from laptop).
I have an issue with MOH multicast in Lab 1 / Task 6.X : everything is OK with unicast MOH but when I want to use multicast I can't hear any MOH. Please note that CUCM shows that it sends MOH as multicast stream :
admin:show perf query class "Cisco MOH Device"
==>query class :
- Perf class (Cisco MOH Device) has instances and values:
MOH_2 -> MOHHighestActiveResources = 1
MOH_2 -> MOHMulticastResourceActive = 0
MOH_2 -> MOHMulticastResourceAvailable = 250000
MOH_2 -> MOHOutOfResources = 0
MOH_2 -> MOHTotalMulticastResources = 250000
MOH_2 -> MOHTotalUnicastResources = 250
MOH_2 -> MOHUnicastResourceActive = 0
MOH_2 -> MOHUnicastResourceAvailable = 250
MOH_3 -> MOHHighestActiveResources = 1
MOH_3 -> MOHMulticastResourceActive = 1
MOH_3 -> MOHMulticastResourceAvailable = 249999
MOH_3 -> MOHOutOfResources = 0
MOH_3 -> MOHTotalMulticastResources = 250000
MOH_3 -> MOHTotalUnicastResources = 250
MOH_3 -> MOHUnicastResourceActive = 0
MOH_3 -> MOHUnicastResourceAvailable = 250
admin:
I did apply multicast confs on HQ/BR1/BR2 routers ("ip multicast-routing" in global conf mode and "ip pim dense-mode" on interfaces with voice stream, etc.).
How can I troubleshoot my issue (I didn't find any troobleshooting example in workbooks for MOH...) ?
Best regards,
SB.
Comments
When BR1-IP-Phone places on hold HQ-IP-Phone :
- I still can't hear MOH at HQ-IP-Phone (multicast MOH issue) ;
- I have very few multicast traces at HQ router and a lot at BR1 router.
Why do I have such traces as HQ-IP-Phone which should receive MOH is not behind BR1 router ???

What's your max hops set to?
also are you hearing dead silience or do you at least get the tone-on-hold?
Hello Aquabrown,
Thank you for your answer.
I set the TTL to the maximum (that is 127 in CUCM, that's why it becomes 126 at HQ and 125 at BR1 - see previous post). I can't hear anything.
Best regards,
SB.
IPSec (without having a GRE encapsulation inside of it) does not support multicast IP traffic. INE uses EzVPN to connect our remote clients back to our racks - which is IPSec only and itself does not support GRE. Therefore the only way you will be able to test MMoH in this sort of lab environment is if you place a call in from your PSTN phone into a BR1 phone (or HQ phone) and have the BR1 (or HQ) phone place the PSTN phone on hold. What you are really doing here is placing the BR1 gateway on hold, and then the BR1 gw is receiving MMoH and it is converted to speech and sent PCM via the PRI to the PSTN, which is then sent Unicast RTP to the PSTN IP phone at your place of study. This is all verified via the means you already have performed.
HTH!
Hi Mark,
Thank you for your answer. I will follow your instructions next time I study.
Best regards,
SB.

Hi Mark,
According to your answer I wanted to check this and tried to hear multicast MoH music from PSTN as you explained (that is by placing a call between PSTN phone and HQ/BR1 phone, and placing the PSTN phone on hold from HQ/BR1 phone). I couldn't ;-! So I tried to hear it using unicast MOH : no more success.
How can I troubleshoot my issue for both multicast and unicast MoH ?
What is funny is that I could hear unicast MoH between HQ an BR1 phones while in AAR conditions, that is using PSTN router... any explanation ?
Thank you for your help,
Best regards,
SB.
Hi Mark,
Any help possible for my case ? Thanks !
Best
regards,
SB.
Hi INE experts,
It would be very nice to help me troubleshooting my case I have for all other labs with MoH...
Best regards,
SB.
Hey SB,
A change was recently made on the PSTN router base config.
Can you try again with the MMoH by calling from PSTN Phone into a BR1 Phone, and pushing Hold on the BR1 Phone (to put the PSTN caller on hold) and then send us the output of BR1 R2 IOS show cmd "sh ip mroute"?
Cheers,
Mark Snow
Hello Mark,
Thank you for your reply. I will try again next sunday and the results and output will be posted here.
Best regards,
SB.
Hi SB,
Can you send us the R1 and R2 (complete) configs, and also confirm what "Base IP Address" you are using for both CUCM Pub MoH and CUCM Sub MoH servers?
Cheers,
Hi Mark,
No more success today for MoH multicasting !!! Once gain, everything is fine with Unicast but I can't hear the music from PSTN phone when I use Multicast.
I proceeded again as you wrote me : I placed call from PSTN to BR1 and I pushed BR1 "On hold" button in order to receive listen MoH music at PSTN phone.
Concerning "Base IP address" :
- Publisher (MOH_2) uses 239.1.1.1 (127 hops max) ;
- Subscriber (MOH_3) uses 239.1.1.2 (127 hops max) .
Please find below :
- my R1 and R2 complete configs,
- "sh ip mroute" outputs for R1 and R2,
- "show perf query class "Cisco MOH Device" " output on Subscriber CLI .
PS : Please remember I use CICP phones running in virtual machines and I
connect to the rack through IPSec (see earlier posts).
Best regards,
SB.

Hi SB,
Try adding this command:
no ip igmp snooping
There has been a long time problem with IGMP Snooping on IOS Routers that also have 4-ESW modules in them. Turn that off and things should begin to work properly as I see the multicast streams in your show commands.
Also I might recommend using a different octet to differentiate between Pub and Sub MMoH Server Base IP Addressing (e.g. Pub 239.1.1.1 and Sub 239.2.1.1).
Cheers,
Hi Mark,
that some lab solution guides give this command for BR1 router, some others not... I will try at next time I study.
Thank you for your answer (and I did notice your recommandation for using a different octet to differentiate between Pub/Sub MMoH Server
Base IP Addressing).
Concerning the "no ip igmp snooping" command, I noticed (too late
But I have one another question concerning this case : I did try too to hear multicast MoH with PSTN Phone placed on hold by HQ Phone, and I proceeded as you told me -> placing a call between PSTN and HQ phones, pushing "On Hold" button on HQ phone, and trying to listen the music at PSTN phone... I didn't succeed with HQ phone !
As there isn't any HWIC-4ESW at HQ router, what could explain that the issue is the same with HQ phone/gateway ? Should I issue this "no ip igmp snooping" command at HQ router too, even if it hasn't any HWIC-4ESW module ?
Best regards,
SB.
SB,
No - the IGMP snooping command wouldn't effect the HQ router. However having ip pim dense-mode on the Loopback interface would effect your ability to hear the MMoH via the PSTN. Put that command on the interface Loopback 0 and try to hear it again!
Cheers,
