[Freeswitch-users] conference_set_auto_outcall with Grandstream phones

[Frederick Pruneau]

Hi all,

I have setup a paging like solution with freeswitch. I am working with 
Grandstream GXP2100 phones. I have enabled "allow auto answer by 
Call-Info" option on the phones. Upgraded phones to the latest firmware. 
When i dial the paging extension, the phones freeze and I cannot do 
anything with the phones. I have to wait 2 or 3 minutes and phones 
hangup. Here is my paging config in my dialplan:

    <extension name="paging">
      <condition field="destination_number" expression="^(12345)$">

        <action application="answer"/>

        <action application="set" data="conference_auto_outcall_timeout=5"/>
        <action application="set" 
data="conference_auto_outcall_flags=mute"/>
        <action application="set" 
data="conference_auto_outcall_caller_id_name=$${effective_caller_id_name}"/>
        <action application="set" 
data="conference_auto_outcall_caller_id_number=$${effective_caller_id_number}"/>
        <action application="set" 
data="conference_auto_outcall_profile=default"/>
        <action application="conference_set_auto_outcall" 
data="[sip_auto_answer=true]user/300@$${domain}"/>
        <action application="conference_set_auto_outcall" 
data="[sip_auto_answer=true]user/301@$${domain}"/>

        <action application="conference" data="$1 at default"/>
        <action application="conference" data="$1 kick all"/>
      </condition>
    </extension>

Is this a bug between freeswitch and Grandstream phones?

Thanks!
Fred
