G.729 normally uses 20ms blocks. They are both usually sent with one block in each RTP packet. If you don't mind a little more latency, put two G.729 blocks into each RTP packet (I'm not sure if Asterisk supports that, but many things do). Then you have a packet every 40ms, a lower bit rate than G.723.1 and better voice quality.

Re: [Asterisk-Users] Where can i get the g.723 codec?
The makers of hardphones prolly get their G72x licensing by using a DSP that already has a license. The DSP can't be that expensive. I wish someone would make a PCI card with something like 8 of these chips on it and sell it cheap. Should be pretty easy to build a codec for Asterisk that uses the DSP card.

Re: [Asterisk-Users] Where can i get the g.723 codec?
I must agree with Eric on this one. I did testing with g723.1 pass thru between two cisco ATA's and you can fit two calls in the same bandwidth as one g729 call. But without a codec in * its pretty much pointless. Also I have emailed these guys about the g723.1 lic they NEVER email back. Even with the crack headed g729 lic setup it still works. bkw On Mon, 3 Nov 2003, Eric Wieling wrote: Licensing info for the G723.1 codec, direct from the holding company that licenses the codec. http://www.dspg.com/technology/LicensePricing.html As you can see they want a LOT of money.

Re: [Asterisk-Users] Where can i get the g.723 codec?
I would be happy to do so for the advantages of G723.1. i.e. great sounding calls at a very low bandwidth. I suspect that the cost of running the data over the PCI bus multiple times would be more than offset by the faster compression/decompression provided by the DSP.

Subject: Re: [Asterisk-Users] Where can i get the g.723 codec?
I hope this doesn't show up twice (posted from wrong mail adr.) Hi Eric, You can actually get boards like this already from companies like Mapletree. Its a hardware pci carrier card where you add the number of DSP modules that you need. This hardware may be a bit 'high end' for most users on this list but several people seems to address this issue pretty often. One card may be equipped with dsp's to handle 488 simultanoeus sessions in any mix of supported codecs(incl. G.723.1 and G729..). I whish that I had the time to make the 'glue logic' thats needed to connect the * codes api with Mapletree busmastering codecs channels. P.S. I am NOT a Mapletree salesperson. -The makers of hardphones prolly get their G72x licensing by using a DSP -that already has a license. The DSP can't be that expensive.
