All,

After reading the Release Notes and then validating with Perfmon counters,
I now know that the initial announcement for Native Call Queuing is sourced
from an Annunciator as unicast, while the following MOH Audio Source and
Periodic Announcement is sourced from an MOH Server.  If the MOH Audio
Source, MOH Server, and MRG are configured correctly, it will use MMOH
successfully.

Relevant Release Notes Section:
http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/rel_notes/9_1_1/CUCM_BK_R6F8DBD4_00_release-notes-for-cucm-91/CUCM_BK_R6F8DBD4_00_release-notes-for-cucm-91_chapter_011.html#CUCM_RF_NE20F57D_00

However, I'm wondering if anyone has any experience with blocking the MMOH
stream from the MOH server, and then serving up a different audio file from
a router.  This is the same tried and true solution we've all been using
for many years to avoid MOH over the WAN.  The difference being the Native
Call Queuing component versus straight up Hold.

What have you noticed or learned from doing this?  Does it just work
seamlessly?  Are there any limitations?

Thanks.
