Re: [VoiceOps] G.729 A/B Experiences

‎Now, why would they do that, when they'd have to transcode every OPUS channel down to 3.1 KHz PCM?  Meanwhile, G.711u is the "native", packetised correlate of what's already flowing down the TDM trunks. -- Alex Balashov | Principal | Evariste Systems LLC 1447 Peachtree Street NE, Suite 700 Atlanta, GA 30309 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ Sent from my BlackBerry.

I think its going to take a big carrier like bandwidth.com or Level3 pushing the SBC/switch vendors to push OPUS. It would be the end all be all codec for voice.

This doesn't necessarily give you any more calls per Kbps, but at least keeps voice and data independent. Wires for dependability, radio waves for bandwidth at the cost of some latency & packet loss. One consideration when using G.729 is how you're going to deliver it to a mostly non-G.729 world. Are your not-quite-broadband customers attached to some PBX that will handle it and send G.711 to your carriers? That's going to cost some CPU or dedicated transcoding hardware. Will your providers accept G.729 and transcode for you? Is there a cost for it? Or will your carriers blindly throw your G.729 at their LCR and hope something sticks? _______________________________________________ VoiceOps mailing list VoiceOps@voiceops.org https://puck.nether.net/mailman/listinfo/voiceops _______________________________________________ VoiceOps mailing list VoiceOps@voiceops.org https://puck.nether.net/mailman/listinfo/voiceops
