These are not documented, but you can check them from the 3CX Console > Settings > Parameters.Is there somewhere in the manual I can find these properties?
DEVELOPMENT_DNTABLE_EXPOSE to 1, and then this section from the console will also show you the DN properties.That's the prefix used by the queue when making callbacks, in case a prefix needs to be dialed before the caller's number, in order to reach the SIP Trunk through an outbound rule.Great thanks for that.
What is CB_DIAL_PREFIX "Used for Call Center Edition to specify the Callback Outbound Rule"?
Is there a call center edition?
