[Freeswitch-users] REFER

22 Jul 2010

      Does any documentation exist for the following dial-plan example?

    <extension name="refer">

      <condition field="${sip_refer_to}">

<expression><![CDATA[<sip:${destination_number}@${domain_name}>]]></expressi
on>

      </condition>

      <condition field="${sip_refer_to}">

                <expression><![CDATA[<sip:(.*)@(.*)>]]></expression>

                <action application="set" data="refer_user=$1"/>

                <action application="set" data="refer_domain=$2"/>

                <action application="info"/>

                <action application="bridge"
data="sofia/${use_profile}/${refer_user}@${refer_domain}"/>

      </condition>

    </extension>

We have a FS gateway in front of a sipXecs PBX. When calls are transferred,
we hear music on hold until the call actually transfers. Then we get dead
air until the new user picks up. We need the remote phone to hear ringback
when calls are transferred.

Thanks,
