AV has indicated they will be supporting G.729, so, does that mean that AV will take in G.711 and compress to G.729 and decompress when you listen to it. Or does it mean that AV can take in G.729 and keep it that way upon playback? Please explain. I have read the post in regard to disk space. It just says that it is upon CPU and proceed with caution using TSP and CM.<br><br><br><br>Sean Poure<br>NEC-Voice Engineering<br>Sr. Systems Engineer<br>714 4846275<br>
Actually, it means all of that. Were just SO flexible
If you configure Unity to default to G729a we will record all messages, greetings and voice names in that format. This saves storage and bandwidth since its a very compressed codec. Ill skip all the warnings about Windows not natively supporting it etc
Also, if we have a message/prompt/greeting that happens to be stored in G711 (i.e. all our prompts are stored in this format since it sounds a lot better or messages could be in the system from before the codec was changed to G729a etc ) we will convert it on the fly to G729a. As such someone calling in on an IP phone across the WAN and cruising around in our conversation will still be getting G729a streamed to their phone even though the prompts are in G711 (MuLaw to be specific). Our CPU takes a small hit to do this conversion but thats about it.
There one extra step here When a call comes into a uOne port (assuming youre using a Call Manager here) a connection type is negotiated. If the phone only supports G711, we have to stream that. If they support G729a, we need to stream that. As such even if we have G729a installed and enabled as our default codec, if a phone connects to us and negotiates a G711 connection type, we will convert the stream to a G711 (i.e. well convert the G729a messages that user is listening to back to 711 for them).
So from Unitys perspective, we should handle any combination of recorded formats and client streaming needs here.
Above and beyond the estimated 5% CPU utilization are there any delays in voice playback time or voice quality. I understand that Unity converts codecs in 8 second chunks. Does this induce any voice issues?
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
