I tried and it still does work. Any simple sample to follow for
transcoding g.729 to g.711a ?

Here's my modfied sip_profiles/external/example.xml
        <gateway name="outbound1">
                <param name="realm" value="155.161.200.188:5070"/>
                <param name="register" value="false"/>
                <param name="inbound-late-negotiation" value="false"/>
                <variables>
                        <variable name="absolute_codec_string"
value="PCMA" direction="outbound"/>
                </variables>
                <param name="reg-id" value="1"/>
        </gateway>


I'm seeing this error ...
