      inbound_late_negotiation should *just work* without setting the

    ya, I know, this was the default setting in my env, it didn't work.<br>

      using this option, set it to false in all sip profiles. Of course,

    I set inbound_zrtp_passthru=false in all sip profiles, still didn't

      fail too :)<br>

    Yes, it is the last resort. <br>
    Do these settings about codec negotiation not take effect when it
    comes to callcenter application?<br>
    <br>

              <font face="Arial">Hi,<br>
                <br>
                I have two clients using different codecs.<br>
                Client A: PCMA, H264<br>
                Client B: G729, H264<br>
                Agent: PCMA,G729,H264<br>
                FS:PCMA,G729,H264<br>
                <br>
                Now agent could only accept calls of client A but not
                from client B. <br>
                When I change the codec order of FS to G729,PCMA,H264,
                then agent could accept client B but not from client A.<br>
                I have tried these settings below and all in vain.<br>
                1) add &lt;action application="set"
                data="inherit_codec=true"/&gt; in diaplan
                (inbound-late-negotiation is true)<br>
                2) add &lt;action application="export"
                data="nolocal:absolute_codec_string=G729,H264"/&gt; in
                diaplan B.<br>
                3) add {absolute_codec_string='G729,H264'} in callcenter
                application, syntax error<br>
                <br>
                Here is the diaplan.<br>
                &lt;extension name="Test Call Center"&gt;<br>
                &nbsp;&nbsp; &nbsp;&lt;condition field="destination_number"
                expression="^555$"&gt;<br>
                &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;action application="sleep" data="1000"/&gt;<br>
                &nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&lt;action application="callcenter"
                data="555@default"/&gt;<br>
                &nbsp;&nbsp; &nbsp;&lt;/condition&gt;<br>
                &lt;/extension&gt;<br>
                <br>
                How can I configure to accept both clients?<br>
                Any advice would be appreciated.<br>
