[Freeswitch-users] conference with inbound portaudio fails on second call

[Jakob]

Hi,

I'm trying to get a conference running with a portaudio inbound leg.

this is my dialplan config that fails on the second call to the 
conference, what am I doing wrong?

<condition field="destination_number" expression="^(3001)$" break="on-true">
                         <!-- Right auditorium -->
                         <action application="set" 
data="conference_auto_outcall_flags=unmute"/>
                         <action 
application="conference_set_auto_outcall" 
data="portaudio/endpoint/in-right"/>
                         <action application="conference" 
data="bridge:$1++flags{mute|endconf}"/>
</condition>

the logs from the second call:
