Hi brian,

thanks for the hint. I added "bypass_media" to my dialplan:


<extension name="PrintVars" continue="true">
<condition field="destination_number" expression="(.*)">
<action application="set" data="effective_caller_id_name=032223930016"/>
<action application="set" data="effective_caller_id_number=032223930016"/>
<action application="set" data="call_timeout=10"/>
</condition>
</extension>

<extension name="FAX Dialout">
<condition field="destination_number" expression="^94(\d{4})$">
<action application="set" data="bypass_media=true"/>
<action application="info"/>
<action application="bridge"
data="sofia/gateway/sip01.voice.ewetel.de/04418000$1 at sip01.voice.ewetel.de"/>
</condition>
</extension>


With this dialplan I get a "480 Temporarily Unavailable" from freeswitch
without forwarding the INVITE to PSTN Gateway.


I use build 5536.
