But in my case, I don't need trascoding because every chanel is in GSM<br>
and voicemail has gsm sound files.<br>
<br>
And for the moment, my Asterisk is not connected to the PSTN, so there<br>
is no trascoding gsm-to-PCM or to analog.<br>
<br>
So I think gsm is a good choice for my scenario, do you ???<br></blockquote></div><br>Hi Alejandro!<br><br>Just to answer your question clearly: Yes, GSM would be a working option for your scenario.<br><br>If you ever need G711 to connect to ISDN the transcoding should be no problem for a P4 class system and for example 30 ISDN-Lines.<br>
<br>But what the others want to say is that buying new phones just to avoid paying for G729 licenses may not be a good idea as the licenses are quite cheap (US$10 for every transcoding you USE at the same time, NOT for every phone you have).<br>
<br>I hope that answers your question.<br><br>Christian<br>
