Administering the Switch Link

Procedure

  1. Open a Web browser and in the Address field type the IP address of the System Management Interface (SMI).
  2. On the Administration menu, click Messaging.
  3. Click Switch Link Administration > Switch Link Admin.
  4. In the Switch Number field, type 1.
  5. In the Extension Length field, select the appropriate length or select Variable for variable extensions.
    NoteNote

    The extension length must match the length assigned to the station on Communication Manager

  6. In the Switch Integration Type field, enter SIP as the type of integration between the Communication Manager virtual system and the Communication Manager Messaging virtual system.
  7. In the Transport Method field, enter either TCP or TLS depending on the method you selected while administering the signaling group.
  8. In the Far-end Connections field, by default only one procr connection is supported.
  9. In the Connection 1 field, enter the IP address of procr. You also need to enter the port number that was administered on procr.
  10. The Messaging Address field displays the IP address of Communication Manager Messaging.
    NoteNote

    The IP address of procr and Communication Manager Messaging is the same. Hence the port numbers must be different. For example, if the Connection 1 port number is set to 5060, you can set the Messaging Address port number to 5061. The port numbers you enter on this Web page must match the values used while administering Communication Manager.

  11. In the SIP Domain field, enter the domain used for Communication Manager and Communication Manager Messaging while administering direct SIP integration.
    NoteNote

    You might want to determine the capacity for Messaging at this point. For the procedure, see Determining the capacity for Messaging.

  12. In the Messaging Ports field, enter the number of voice ports the Communication Manager Messaging virtual system uses for mailbox connections to the Communication Manager virtual system.
  13. In the Switch Trunks field, enter the total number of trunks for Communication Manager.
  14. Click Show Advanced Options

    The system displays advanced options that you need to administer.

  15. In the Quality of Service field, type a value for Call Control Per Hop Behavior (PHB) and Audio PHB or accept the default values. The value you enter for both the fields sets the quality of service level for call control messages and audio streams respectively on networks that support this feature. The value for both the fields must be in the range 0 to 63. The value must match the corresponding number configured for the network region used by the messaging signaling group on the switch.
  16. In the UDP Port Range field, enter a starting UDP port number for RTP. The end port number is calculated automatically.
  17. If you have configured SRTP for messaging, in the Media Encryption field, enter the type of Secure Real-time Transport Protocol (SRTP) encryption for messaging.
    ImportantImportant

    You need to enable the SRTP feature in the change customer-options form and set the media encryption type in the change ip-codec-set form on Communication Manager.

  18. If you want to enable DTMF transport via SIP INFO method, in the SIP INFO FOR DTMF field, enter Accept.
    ImportantImportant

    You need to set the DTMF over IP field to out-of-band.

    NoteNote

    This field is set to Ignore. If you change it to Accept, then any digits received from rtp-payload will be ignored.

  19. Click Save.
