The general idea is that you work out how many licenses you will need on your busiest day and then buy a couple of extras. Most of the time you will not be using what you have paid for. The G.729 monopolists have made enough money out of their week's work, so why give them more?
A better idea is to use a different codec, such as GSM, iLBC or even ulaw (if you have the bandwidth), and ignore G.729 completely. You can add several choices in a list and allow the link to negotiate. The SIP channel will try your codec choices in order of preference but IAX2 will just pick one (usually ulaw). Adding a few lines of code will allow the IAX2 channel to respect the code preference order you select. If your supplier will only talk G.729 then switch to one that will allow you to use a different codec. There are plenty to choose from these days. -- _/ _/ _/_/_/_/ _/ _/ _/_/_/ _/ _/ _/_/_/ _/_/ _/ _/ _/ _/_/ _/ K e v i n W a l s h _/ _/ _/ _/ _/ _/ _/ _/_/ [EMAIL PROTECTED] _/ _/ _/_/_/_/ _/ _/_/_/ _/ _/ _______________________________________________ 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
