Interesting point. Are there VoIP terminators that can accept iLBC or where can I find them? Are there any hardware endpoints that can handle this codec? Tjapko.

I have had *zero* voice quality issues with iLBC. I have had voice quality issues due to links that were full, but that's not iLBC's fault. The only reason I can see using g.729 these days is for low-bandwidth interoperability with commercial VOIP equipment that doesn't use iLBC. Seriously. The difference between 11-13kbps for an iLBC conversation vs 8kbps for g.729 is negligable to me. Maybe if you had a thousand calls pumping out your connection, but then again the $10k you spent on g.729 licenses can probably buy a slightly faster link. :-) Regards, Andrew _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users --- Incoming mail is certified Virus Free.
