Symptom

Migrating from 3900 E&M live-MOH to 4431 FXO live-MOH Needs to be configured on call-manager-fallback as this is not a CME (which uses telephony-service). Currently there is no feature to support this operation outside of CME on 4431. config required: interface Loopback0 ip address 1.1.1.1 255.255.255.255 ip pim sparse-dense-mode ! interface GigabitEthernet0/0/0 description LAN interface Primary backup interface GigabitEthernet0/0/1 ip address 10.15.55.80 255.255.255.224 ip pim sparse-dense-mode negotiation auto ! interface GigabitEthernet0/0/1 description LAN interface Secondary mac-address a8b4.56a9.2440 ip address 10.15.55.80 255.255.255.224 ip pim sparse-dense-mode negotiation auto voice-port 0/2/3 signal loopStart live-feed no vad description Live MoH Feed ! dial-peer voice 1152 pots description HQ MOH via TCL Script destination-pattern 1152 port 0/2/3 forward-digits 0 ! dial-peer voice 1155 voip description HQ MOH via TCL Script preference 1 destination-pattern 1155 session protocol sipv2 session target ipv4:10.15.55.80 incoming called-number 1155 dtmf-relay h245-alphanumeric codec g711ulaw no vad ! call-manager-fallback secondary-dialtone 9 max-conferences 8 gain -6 transfer-system full-consult timeouts interdigit 5 ip source-address 10.15.55.80 port 2000 max-ephones 1000 max-dn 1800 dual-line transfer-pattern .T voicemail 91212yyyyyyy call-forward pattern .T call-forward busy 91212yyyyyyy call-forward noan 91212yyyyyyy timeout 18 moh-live dn-number 25 out-call 1152

Conditions

with this configuration (in symptoms) you see PCM capture indicates s-in passes through s-out but it is not switching on the media plane to other interfaces as it was successful doing with the E&M solution in the 3900. UPDATE 27-Jan-2021 The issue is more technical. When introduced the SRST/CME feature for 44xx assumed phones which would locally register to the gateway and then the MOH woud be delivered to those devices as needed while in CME or SRST mode of operation. The distinction here is: a) we have ZERO phones registered to this gateway and b) in non-SRST mode the ask is for us to be able to deliver live-MOH from the FXO port through the DSP to unicast MOH which is exported from this HQ GW to subtending branch GWs (via a WAN connection - so no multicast allowed) for use by those branch gateways. (Again this happened to work in the 3900 platform - although I am not certain it was supported it just worked because the backplane was not split into control and data). The enhancement would need to work in the scenario in the previous paragraph.
