[Details] Is an ECMAScript expression which returns an identifier of a connection or conference. The default value of the "conid" attribute is "_event.source", which will be the connection that generated the previous event (typically a connection.CONNECTION_CONNECTED event). A connection will be allocated for the dialog being launched, and this connection will be bridged to the connection or conference specified by "conid". For more information about connections and bridges, refer to Section 10. [Attribute Name]
