Thanks for your comment about codecs....I tell you I can't use G.711<br>
because I use a WAN link, and this is a wide band codec.<br>
<br>
Is GSM codec totally free (avoid to pay for any license) ???</blockquote><div>yes !<br>Is there a WAN between your hardphones and Asterisk ? <br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

<br>
Thnks again.<br>
