Thanks John. From the sound of it, the "shared-talk" feature is the missing piece to the puzzle. It doesn't look like I can test this out using the Dashboard, which must be the reason why there's no mention to Shared-Talk anywhere within.

I have a client app that is essentialy a Media Player (Play, Pause, Resume) whereby the agent can play a recorded message at will. I will modify my app to use the Shared-Talk button and see how it goes.

I'll keep you posted of the results. Thanks again for your help.

Your assumption is correct.

I have a physical station (A) making an outbound call to an external phone number (B).

A & B are involved in a phone conversation, and the agent at A wants to play a recorded message from the server over the active conversation.

In this case I'm using the DMCC Dashboard to create the DMCC device (C) registered to the extension of A in dependent mode.

Once registered I want to play the audio file to both A & B, so I hit Play under the "Play Capabilities" of the Server Media tab.

As for where am I listening for Audio, I'm listening at both A & B.

No, we haven't packet sniffed near AEServices to determine where it's trying to send the RTP yet.

Based on my description above, is this something I should be able to do? By all appearances it is. It just seems like I'm missing something in the configuration, or perhaps there's something in the network interfering.

I'm confused... is this required for Server Side Media Controls? Everything I've read indicates that the media is played from the Server and these parameters cannot be changed. I'm under the impression from reading the "Mastering the DMCC Dashboard" document among other things, that the playing of a recorded file is performed at the server and not the client. Is this not the case?

"When a DMCC device is registered in Server Media mode, Communication Manager directs the media streams at the extension to the AE Services server. Server-side media control allows you to take advantage of AE Services media control resources to record calls, play messages and collect DTMF tones."

"In Server Media mode, the RTP media parameters are predefined and cannot be amended by the client application."

I'm attempting to inject an audio file into a conversation using the Server Media control of the dashboard. Everything appears to be working, only I don't hear the audio. I can see from the logs and event window that the File starts playing and Stops playing when it hits the end, but I never hear my recording. It's almost like the RTP is going somewhere else???

Any ideas?
