hi all we're setting up a rather large end-user VoIP system, and due to pressure from norwegian telephony authorities, we consider choosing something instead of G.711A, possibly G.729. does anyone know if it is possible to test-drive G.729 without paying Digium for it? roy
I personally think for a codec that's almost 1/3 the size of ULaw, the quality is great. I consider ULaw above telephone quality, and g729 to be at telephone quality. But just 5 minutes ago I moved a user over to g729a. Changed the SIP000xxxx.cnf file for the Cisco phone, but forgot to change the dtmfmode in sip.conf from inband to rfc2833 and Asterisk wigged out with 300,000 messages about dtmf and such. Once I fixed that, he said the quality was horrible. He could definitely hear the difference and hated it. Although I could hear him fine, sounded good enough to me. Not sure what that was about. I guess mileage will vary. Have you looked into that open-source implementation of G729? There was something on the WIKI about 3 different implementations of it. One being where you paid license per channel fees, one that was free/open source, and another I can't remember. Check the WIKI. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Roy Sigurd Karlsbakk Sent: Tuesday, October 19, 2004 10:48 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [Asterisk-Users] test-driving G.729? hi all we're setting up a rather large end-user VoIP system, and due to pressure from norwegian telephony authorities, we consider choosing something instead of G.711A, possibly G.729. does anyone know if it is possible to test-drive G.729 without paying Digium for it? roy _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Seriously it's not that expensive and if it doesn't work it doesn't work -- I piss away $20 on beer and wings the odd time, or a few hours of pool... -A.

Any such implementation is called a "Hack", if that is what one would like to call it. There are sevral such hacks available but none of them really work. I tried them. The Audio quality is miserable with such implementations. Seshu Kanuri -------------------------------------------------------- NOTICE: If received in error, please destroy and notify sender.

Remember that we discussed this at length over about 3000 posts. I again reiterate that it is called a "HACK" and I am Ok with what you are doing. Kevin and Others in this forum has made the licensing point very clear. All I am saying is let us call a spade a spade.

I've been using this http://www.readytechnology.co.uk/open/g729/ since the author (of the asterisk adaptation) posted on the list, and it sounds great. If anyone wants to try G729 before buying the licenses for commercial use, that's the way to go.
