9.1 Audio files

[Rhonda Wassman]

I'm looking for information on what happens when the audio files coming over from the server to the computer. We have a Development system set up and we are trying to document if/how this could break the voicemail. If you have experience with this happening, please let me know. We are running 9.1 currently. I was wondering if possibly this has been a problem with 8.1? Thanks.

Which audio files are you referring to?

[Rhonda Wassman]

The audio file setting as you RDP in to the server (the ones transfered over for sound).

You mean the audio redirection performed by the remote desktop client? (This is audio streams, not files.) This is documented in KB928046. ShoreTel uses a custom audio driver to provide 255 wave devices connected to calls. This driver is unloaded, making these devices unavailable. Since VM uses these devices to play back AA prompts and voice mails, the VM system can break.

I think it would have a relation to a windows driver.

RDP loads the drivers as it connects to the machine, so if you have the sound option on the Remote Desktop Connection set to "Bring to this computer" (click the options >> button, then click local resources tab, then select remote computer sound "leave at remote computer") it will bring the voice mail sound to your computer. I have never tested why it does this because it would take down the voicemail prompts.

I dont know enough about windows drivers or how RDP really works to provide you with a better answer. Other than it will bring the drivers to your machine.

I hope i point you in the right direction.

We are able to bring the sound over and still get in to voicemail (on our development system). Does it only affect auto attendant?

[Rhonda Wassman]

How are other users solving this issue? Are they using the MS hotfix? Disabling Audio Mapping at the server? Using a different product?

[sean]

You can save an RDP Connection and make sure the sound options is left at "leave at remote computer" then you can use that to RDP to the sever.

Does this help you?

Wasn't this issue fixed by Microsoft in Win2k3 SP2?

[Miersk]

with the service pack, there is a registry setting.
