When I start a conference from xml dialplan like this - everythiing works (plays audio, I'm asked to enter PIN):
```
<extension name="conf-test">
<condition field="destination_number" expression="^(\d+)$">
<action application="conference" data="arthur@default-en+1234+flags{endconf|moderator}"/>
</condition>
</extension>
```
But when I use fs_cli to call to my mobile number, then joining to conference - I don't hear audio (woman's voice "You are only one person in the conference"), and what is more important - I'm not asked to enter PIN code. Whyy????
```
originate {origination_caller_id_number=8080000000}sofia/gateway/mygateway/my-mobile-number &conference(test@default-en+1234+flags{endconf|moderator})
```
I need to use API to join a mobile phone number to conference, and ask him to enter a PIN number (becouse sometimes phone number can be offline, but owner can turn on a voicemail service, and voicemail will record conversation untill it became full (up to 1 hour)). I don't want to call to voicemail for 1 hour becouse of money.
Thanks.
