I no longer have access to that router, but here is the TAC recap. The only thing that needed to be added was PIM on the Service-Engine port of the NIM..

Hello Greg,
Thanks for hopping on our call.
Find the detailed overview of the WebEx below in addition to every item we discussed on the call about the LMR hootie feature on IOS-XE.
As agreed let me know when you have finished testing!
Thanks,
### Problem Description
Customer is configuring LMR/Hootie Feature for ISR4000 for the first time to certify this deployment to sell to customers
### Platform Info
4321 - 16.9.1
### Call Flow
Radio > E&M (voice-port 0/1/0) > 4321 > Gig0/0/1 (192.168.100.254) > Multicast (239.10.10.24)
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx> No audio
### Action Taken
Upgraded from 16.3.6 to 16.9.1 as 16.3 was the introduction of the Hootie feature on IOS-XE and 16.7+ have alot of fixes.
Added PIM to the service-engine interface which is the L3 internal interface for the DSP/PVDMs on the NIM Card.
Checked a PCM and can hear SIN traffic with audio so radio and cabling is good for voice port.
Checked the hootie feature with 'show platform hardware qfp active feature sbc hootie group' and I don't see any problems with replication or drops performed by the DSP as there are no drops observed.
Checked 'sh ip igmp member' commands and we see the local endpoint joined to the multicast network properly.
Checking the global drop counters of 'show platform hardware qfp active statistics drop' while I don't see the DSP incrementing failures but I do see the drops for Ipv4mcNoRoute (No IPv4 Multicast Route)
Noticed the VIF was .254 making the internal VIF+1 .255 which is broadcast. So we shut it down and changed to .253 so VIF+1 is .254 then shut/no shut the voice-port to restart the call. Drops still occurred.
'show ip mroute' shows no output so we enabled 'ip multicast-routing distributed' and now we see valid ViF and routes.
At this point testing worked as expected and the Ipv4mcNoRoute drops are gone after clearing 'show platform hardware qfp active statistics drop clear' and doing further testing.
I also used the test command 'test voice port 0/1/0 inject-tone network 1000' sent audio from the DSP towards the IP LAN / Multicast.
