Hello all,
I had uploaded a new MOH, It seems that the uploaded message status is fine( status ok in all output file list).
But someone put me in hold, I just hear "bip bip bip".
Maybe is there any format problem ?
What is exactly the require file format?
Thanks & Regards,
Etienne

Hi,
Try to do a reset of the MOH server (I assume you are using CM not CCME)

Hi Etienne,
There are a number of reasons why callers hear Beeps instead of MOH (especially for Internal calls). Have a look;
Restrictions for Music on Hold
IP phones do not support multicast at 224.x.x.x addresses.
Cisco Unified CME 3.3 and earlier versions do not support MOH for local Cisco Unified CME phones that are on hold with other Cisco Unified CME phones; these parties hear a periodic repeating tone instead.
Cisco Unified CME 4.0 and later versions support MOH for internal calls only if the multicast moh command is used to enable the flow of packets to the subnet on which the phones are located.
Internal extensions that are connected through an analog voice gateway (Cisco VG 224) or through a WAN (remote extensions) do not hear MOH on internal calls.
Multicast MOH is not supported on a phone if the phone is configured with the mtp command or the paging-dn command with the unicast keyword.
From this excellent CME doc;

Hi,
Thanks for your reply.
Nevertherless, I think MOH is already well configured because it usually works.
I just tried to add a new file in the MOH audio source and changed it in a profile.
I changed again to the first MOH audio file and it does work normally.
My file is actually in the right format : 8 bits, 8 khz, mono CCITT u-law.
I really don't know where the problem is comes from.
