[Freeswitch-users] No Early Media Ringback

[Praveen Ray]

Hi All
I am using Freeswitch 1.0.6 with Vitelity as inbound/outbound provider. My
Inbound calls route properly to extension 1000, however, the caller does not
hear the extension ringing. The extension at 1000 does ring however and once
I pick up the call, the conversation proceeds normally. I just can't figure
out why the caller hears silence during phone ringing. I have tried putting
instant_ringback in dialplan/public.xml:

<extension name="vitel-inbound">
        <condition field="destination_number" expression="">
                <action application="set" data="instant_ringback=true"/>
                <action application="transfer" data="1000 XML default"/>
        </condition>
  </extension>

The log lines during inbound calls show:

where 5087203445 is my inbound DID. Can someone please help decipher what
