This is what I did, i installed an the open source codec. but legally, your supposed to buy a license.
1) download 723 and 729 codec
http://kvin.lv/pub/Linux/Asterisk/
2) copy both codecs to /usr/lib/asterisk/modules
3) restart asterisk
/etc/init.d/asterisk restart
4) verify its working. as long as 723 and 729 display numbers and not S, it's working
asterisk1*CLI> show translation
Translation times between formats (in milliseconds)
Source Format (Rows) Destination Format(Columns)
g723 gsm ulaw alaw g726 adpcm slin lpc10 g729 speex ilbc
g723 - 2 2 2 3 2 1 3 8 - 12
gsm 8 - 2 2 3 2 1 3 8 - 12
ulaw 8 2 - 1 3 2 1 3 8 - 12
alaw 8 2 1 - 3 2 1 3 8 - 12
g726 9 3 3 3 - 3 2 4 9 - 13
adpcm 8 2 2 2 3 - 1 3 8 - 12
slin 7 1 1 1 2 1 - 2 7 - 11
lpc10 8 2 2 2 3 2 1 - 8 - 12
g729 8 2 2 2 3 2 1 3 - - 12
speex - - - - - - - - - - -
ilbc 8 2 2 2 3 2 1 3 8 - -
5) allow the codec in sip.conf under [general]
disallow=all
allow=g729

Good Day,
I am new to Asterisk and I need help in configuring codecs in Asterisk. I also will need to buy the license for G 729 codec and need to put that key in Asterisk. Can someone please provide the step by step instructions for the codec configurations?
Also I am having problems forwarding calls to landline or cellular numbers. As soon as the preson on the forwarded end picks up the call drops - what can cause this and what is the solution?
Thanks
Wyatt
