[Freeswitch-dev] No ringback tone, when calling

      No ringback tone, when calling

Hello,

i have the following problem:

I use a phone on line port of LinkSys Spa 3102, which is registered with 
number 60 on freeswitch.
I can hear a ringback tone, when I?m calling another registered phone 
for example 61 (see dialplan extension Call Voip).
I cannot hear the ring tone on the phone connected to the Spa 3102, when 
I'm calling special number 70 leading to a self implemented freeswitch 
module
(see dialplan Doing Something).
This problem doesn't appear using X-Lite or an Siemens Voip telephone.
My module does a preanswer as in the code shown below but something must 
be different - maybe I have to add somehting to the callhandling.
Does anyone have an idea ?

Greetings

Here is a snippet of my dialplan:
-------------------------------------------------
<extension name="Doing Something">
<condition field="caller_id_number" expression="^6[0-9]$" />
<condition field="destination_number" expression="^7([0-9])$" >
<action application="set" data="call_timeout=120"/>
<action application="set" data="hangup_after_bridge=false"/>
<action application="set" data="ignore_early_media=true"/>
<action application="doingSomething" 
data="DoingSomething,5$1,${destination_number}"/>
</condition>
</extension>

<extension name="Call Voip">
<condition field="destination_number" expression="^.*$" />
<condition field="caller_id_number" expression="6([0-9])">
<action application="bridge" 
data="sofia/internal/${destination_number}@${amtsleitung_5$1_ip_address}:5061" 
/>
<action application="answer"/>
</condition>
