CTI Remote Device (CTIRD) Call Flows Unified Communications Manager supports the separate calling party number and billing number feature when users are added as CTI Remote Device. Each CTI Remote Device is configured with the user directory number (DN) (for example, 2000) and a remote destination that represents any off-cluster device (for example, a PBX phone with the number +1 408 111 1111). When a call is initiated from the PSTN network to a CTIRD line, Unified Communications Manager looks for FROM and PAID header information. The FROM header contains the external presentation name and number and PAID contains the identity of the user (that is a user’s DN or DDI). If FROM and PAID headers have different numbers and Enable External Presentation Name and Number check box is checked in its SIP profile and Display External Presentation Name and Number service parameter value set to True, then Unified Communications Manager displays the FROM header information on the called device. In the same way, if any one option is disabled,Unified Communications Manager displays PAID header information on the called device. Similarly, in the outgoing call scenario a user calls from Remote Destination (CTIRD line) configured with External Presentation Name and External Presentation Number on Directory Number configuration page to a PSTN network through a SIP trunk with Enable External Presentation Name and Number configured in its SIP profile. Then, Unified Communications Manager send the External Presentation Information configured on the Directory Number Configuration page in the FROM header of the outgoing SIP message to display on the called device. If Enable External Presentation Name and Number check box is unchecked, then Unified Communications Manager sends the directory number information in the FROM and PAID to display on the called device and configured External Presentation Information in the X-Cisco-Presentation header. If you check the Anonymous External Presentation check box, the configured External Presentation Name and Number are removed from the respective fields and external presentation displayed as anonymous on the called device. For more details on Configuring External Presentation Information, see the Configure Directory Number chapter in the System Configuration Guide for Cisco Unified Communications Manager.
