If Asterisk has to rip apart or assemble a g729 stream for any reason, you'll need a license to do so. If you need to do it twice in the same period of time, you'll need two. Typically speaking you will need a license any time Asterisk needs to convert betwen g729 and any other codec. Your FXS and FXO ports use the slinear audio format so any time you want to use one of the ports and connect to a VOIP provider using g729 you'll be using a license. Also, a license will be required any time Asterisk needs to "hear" the audio stream from a g729 source. This means if you want Asterisk to listen for silence or voice, detect DTMF or mix audio from several sources. If Asterisk is able to take a g729 frame and pass it along without doing anything to it, no license is required. Those last three paragraphs can be summed up by saying "a g729 license is required any time Asterisk needs to transcode to or from a g729 audio format." HTH, -A.

Long answer: Zap interfaces use G711 and do not need G729 to work. Only if you plan to connect SIP or IAX phones from outside your local network do you really need voice compression. -- Telecomunicaciones Abiertas de Mexico Carlos Chavez Director de Tecnologia +52-55-91169161 Ext. 2001 -------------- next part -------------- A non-text attachment was scrubbed...

Essentially, need a license for each codec translation, including gsm sounds -> g729, etc. The TDM card does not support g729, therefore you would need to count the number of destinations that _only_ use g729 to determine the number of licenses. An FXS phone on the TDM card listening to asterisk sounds won't need any, but the same phone talking to another g729 user will need one. Likewise, the TDM FXO port doesn't support g729.
Thanks everybody for answering me. Yes, I plan to connect SIP phone outside of my network. Infact, I am going to use Asterisk as my PSTN gateway and voice mailbox. Also, I have plan to add two more FXO card when I will have bigger network. Sounds like, I should get two liscences at this moment.
