[Freeswitch-users] How to configure media bypass when using mod_callcenter

10 Apr 2012

      Hi Maestros,

i'm using mod_callcenter to realize a simple senario, pstn user call to
media gw, then go to queue number 7000 of fs, then fs hunt a idel
agents(registered users) to accpet the call. it works fine.

however, i would like to make the media bypass the fs after the agent
answer the call, i.e. media-gw<->agent, however, from the trace,the media
still go via fs. from the trace, i saw when fs make the call to agent, the
fs initiate a new "INVITE"  with itself IP address as the connect ip
address in SDP, which caused the bypass failed. (in the attahed trace, .159
is the fs, .50 and .117 are two registered users).

i have configure below, and if two agent call for each other directly, the
media did bypass fs.

internal.xml
    <param name="inbound-bypass-media" value="true"/>
    <param name="inbound-proxy-media" value="false"/>

othe configuraton as following,

dial plan:

    <extension name="7000_Queue" >
   <condition field="destination_number" expression="^7000$">
       <action application="answer"/>
       <action application="playback"
data="/usr/local/freeswitch/sounds/custom/8000/transfer_to_agent.wav"/>
       <action application="callcenter" data="7000_Queue@localhost"/>
       <action application="system" data="mkdir -p
$${base_dir}/recordings/archive/${strftime(%Y)}/${strftime(%b)}/${strftime(%d)}/"/>
   </condition>
</extension>

callcenter.conf.xml:

<configuration name="callcenter.conf" description="CallCenter">
    <settings>
        <!--<param name="odbc-dsn" value="dsn:user:pass"/>-->
    </settings>

    <queues>
        <queue name="7000_Queue@localhost">
            <param name="strategy" value="round-robin"/>
            <param name="moh-sound" value="$${hold_music}"/>
            <param name="time-base-score" value="queue"/>
            <param name="max-wait-time" value="0"/>
            <param name="max-wait-time-with-no-agent" value="0"/>
            <param name="tier-rules-apply" value="false"/>
            <param name="tier-rule-wait-second" value="300"/>
            <param name="tier-rule-wait-multiply-level" value="true"/>
            <param name="tier-rule-no-agent-no-wait" value="false"/>
            <param name="discard-abandoned-after" value="60"/>
            <param name="abandoned-resume-allowed" value="false"/>
        </queue>
    </queues>
