Hi Klaus,<br><br>I tried your patch that uses the amr codec.<br>Managed to build it with Asterisk 1.4.13.<br>We have a 3G gateway that talks SIP to this Asterisk and on the other side a plain X-Lite that registers with this Asterisk (using g711 alaw).
<br><br>I can't call X-Lite. Error: "chan_sip.c:2963 sip_call: No audio format found to offer"<br>However, the amr codec seems to be available:<br><br> INT BINARY HEX TYPE NAME DESC
