I have tried the nb_conference example in the default.xml but I think I am doing something wrong. when i transfer to that extension it drops me into a single static conference of the variable . what do i need to add or change to prompt my callers transfered to the nb_conference to enter a 4 digit conference number without pin that gives them the same options as my static conferences on the default profile? I know play and get digits must be involved but would appreciate the help. thanks.
<extension name="nb_conferences">
<condition field="destination_number" expression="^\*(30\d{2})$">
<action application="answer"/>
<action application="conference"
data="$1-${domain_name}@default"/>
</condition>
</extension>
