iLBC Codec Support for MGCP

I was recently troubleshooting the iLBC codec negotiation issues between a MGCP Gateway & CIPC Phones in my environment. Unlike the regular Codecs, you need to enable iLBC ( and AMR-NB Codec) for an MGCP Gateway to use it during the codec negotiation phase.

Here is a good Cisco Link for the same:

Multicast MOH from Flash

Here is the config with my notes:

sh flash | i music-on
ccm-manager music-on-hold
call-manager fallback
moh music-on-hold.au
multicast moh 239.1.1.1 port 16384 route 10.10.201.1 10.10.110.2

! 239.1.1.1 port 16384 will be applicable for the First MOH Server. If you use SUB,
! it will be 239.2.1.1 port 16384. This is incrementing on IP add. Also beware that
! if you're using different CODEC, then this will be 239.1.1.3. So 3 Golden Rules by Vik:
! 1. Have only 1 MOH Server for BR1 site
! 2. Use only audio source 1 file system wide
! 3. Put this MOH Server in G711 DP

debug ephone moh
debug ccm-manager music event
sh ccm-man music

! The best way to block the multicast now coming from HQ is to remove PIM config from the
! HW RTR PVC.
! When you get Tone-ON-Hold -- CCM Has Issues
! When Dead Air -- Infra has issue
! You cannot XCode Uni/Multi MOH Stream. Multicast MOH Stream is exempt from Location CAC Deduction
