Re: [asterisk-users] Choppy MOH (Cisco gateway)
Actually the problem was somewhere in the Cisco equipment, as the service provider has confirmed. Some option in their device to conserve bandwidth by compressing voice data was causing this choppyness.

VAD option on Cisco Gateways maube are causing this.
