Prolog information
Metadata
Keywords:
  1. Type add signaling-group n, where n is the signaling group number.
    ADDITIONAL INFORMATION:
    The system displays the Signaling Group screen.
  2. In the Group Type field, type sip.
  3. In the Near-end Node Name field, type the node name of the procr.
    ADDITIONAL INFORMATION:
    The node names are administered on the Node Names screen and the IP Interfaces screen.
  4. In the Far-end Node Name field, type the far end Session Manager name.
    ADDITIONAL INFORMATION:
    Leave this field blank when the signaling group is associated with an unspecified destination.
  5. In the Near-end Listen Port field, type the port number depending on the transport method.
    ADDITIONAL INFORMATION:
    For example, enter 5060 for TCP/UDP and 5061 for TLS.
  6. In the Far-end Listen Port field, enter the number entered in the Near-end Listen Port field.
  7. In the Far-end Network Region field, enter a value from 1 to 250 or leave the field blank.
    ADDITIONAL INFORMATION:
    Identify the network assigned to the far end of the trunk group. The far-end network region is used to obtain the codec set for negotiation of trunk bearer capability.
  8. In the Far-end Domain field, type the name of the IP domain that is assigned to the far end of the signaling group.
    ADDITIONAL INFORMATION:
    For example, to route Session Manager calls within an enterprise, the domain assigned to the proxy server is used. For external SIP calling, the domain name can be the name of the SIP service provider.
    Leave this field blank when you do not know the far-end domain.
  9. In the DTMF Over IP field, specify the DTMF digits for transmission .
    ADDITIONAL INFORMATION:
    The valid options for SIP signaling groups are:
    • in-band: All G711 and G729 calls pass DTMF in-band.
    • out-of-band: All IP calls pass DTMF out-of-band.
    • rtp-payload: RFC 2833 specifies this method. By default, RFC 2833 is the default value for newly added SIP signaling groups.
    For more information about the options, see Avaya Aura® Communication Manager Screen Reference .
  10. Save the changes.
  11. Type add trunk-group n, where n is the trunk group number.
  12. In the Group type field, type sip.
  13. In the TAC field, type the trunk access code number.
  14. In the Service type field, type tie.
  15. In the Signaling Group field, type the signaling group number that you configured earlier.
  16. In the Number of Members field, type the number of members that you want to assign for the trunk.
    ADDITIONAL INFORMATION:
    Enter a value in this field only when member assignment is auto.
  17. Save the changes.
