Read the MoH section in SRND, it should clear your doubts. After reading that if you still have any questions please feel free to post back.

MoH Selection Process

This section describes the MoH selection process as implemented in Unified CM.

The basic operation of MoH in a Cisco Unified Communications environment consists of a holder and a holdee. The holder is the endpoint user or network application placing a call on hold, and the holdee is the endpoint user or device placed on hold.

The MoH stream that an endpoint receives is determined by a combination of the User Hold MoH Audio Source of the device placing the endpoint on hold (holder) and the configured media resource group list (MRGL) of the endpoint placed on hold (holdee). The User Hold MoH Audio Source configured for the holder determines the audio file that will be streamed when the holder puts a call on hold, and the holdee's configured MRGL indicates the resource or server from which the holdee will receive the MoH stream.

As illustrated by the example in Figure 7-3, if phones A and B are on a call and phone B (holder) places phone A (holdee) on hold, phone A will hear the MoH audio source configured for phone B (Audio-source2). However, phone A will receive this MoH audio stream from the MRGL (resource or server) configured for phone A (MRGL A).

Hi Santiago,

The question is lacking of information but assuming one phone is registered on CUCM and another on the gateway (CME), it depends, if the phone on CUCM push the hold buttom the hold is from CUCM, on the other hand  if the phone on CME push the hold buttom the hold is from CME.

Please describe the topology deeper to be able to assist you.

 

PhoneA---CUCM---gateway --- WAN---Gateway (audio in flash memory)--PhoneB

 

PhoneA put the call in hold to PhoneB

 

and PhoneB put the call in hold to PhoneA
