Distortion during Unity prompts

Hello,

I have Unity version 7.0(2) integrated with Call Manager version 6.1.3.  We are experiencing distortion when we hear the Unity system prompts.  We are making on-net calls over the WAN.  We only experience this when we call over a WAN link to listen to voicemessages.  Is there a QoS setting i can configure on the routers specific to this issue or could something else cause this?

Thanks

Re: Distortion during Unity prompts

What codec are you using to make these calls to Unity over the WAN? If you are using G.729 over the WAN, do you have Unity configured to also use G.729. The Unity prompts are recorded in G.711 and playing those over a G.729 call will cause distortion of the prompts.

This document shows how to change the codec for the system prompts (documentation for 7.x is the same for 5.x):

Thanks,
