The SBC does not support multi-cluster deployments for T-SBC and M-SBC. Currently, the S-SBC is able to resolve a single FQDN for the DSP cluster and the policer cluster.


When using the dnsGroup LOCAL resolution, you cannot configure more than four active T-SBCs/M-SBCs since the DNS Group LOCAL entries are limited to a maximum of four entries. If you need to enable more than four active T-SBCs/M-SBCs, use an external DNS for resolution.

Note

The options on this window are visible and configurable only for distributed SBC deployments.

Use the Cluster - Type window to configure cluster profiles that define how the distributed signaling SBC (S-SBC) should contact its peer clusters in the D-SBC deployment. These cluster profile represents the policer (M-SBC) and dsp (T-SBC) cluster with its point of contact (FQDN). You can also configure a cluster to invoke an MRF as a transcoder for the D-SBC deployment. Refer to Invoking MRF as a Transcoder for D-SBC for more information on this type of deployment.

On the SBC main screen go to All > System > DSBC > Cluster > Type. The Type window opens.


Creating a Policer Cluster Type

To establish a connection between an S-SBC and an M-SBC cluster, create a Policer cluster type. In the Create New Type window:

  1. Click New Type. By default, the Create New Type window opens for the Policer profile type. 

  2. Select the State to enable or disable the profile.
  3. Enter an FQDN for the M-SBC cluster.
  4. In DNS Group, choose a DNS Group.
  5. Click Save.
Note:

If you later need to edit or delete a Policer cluster, first set its State to Disabled. Set the State back to Enabled after you edit the Policer cluster.

Creating a DSP Cluster Type

To establish a connection between an S-SBC and a T-SBC cluster, create a DSP cluster type.

  1. Click New Type. The Create New Type window opens. 

  2. In Name, choose DSP.
  3. Select the State to enable or disable the profile.
  4. Enter an FQDN for the T-SBC cluster.
  5. In DNS Group, choose a DNS Group.
  6. Click Save.
Note:

If you later need to edit or delete a DSP cluster, first set its State to Disabled. Set the State back to Enabled after you edit a DSP cluster.

Creating an MRF Cluster Type

The D-SBC can inter-operate with a third-party transcoding platform called a Media Resource Function (MRF) to transcode audio and relay video/T140. Refer to to Invoking MRF as a Transcoder for D-SBC for more information on this type of deployment. 

To establish a connection between an S-SBC Cluster and an MRF, create an MRF Cluster Type. You have the option to configure the routing type as either an FQDN or as an IP address.

  1. Click New Type.
  2. Select the Name as MRF.
  3. Select the State to enable or disable the profile. Continue with either the FQDN or IP address steps as appropriate.

To create an MRF cluster with a Routing Type of FQDN:

  1. Select the MRF Routing Type as FQDN.

  2. In the MRF TG Name drop-down menu, choose the trunk group to use for MRF signaling.
  3. In Mrf Request URI, enter the Request URI to be sent in the MRF INVITE request.
  4. Enter the MRF Port number for the MRF server.
  5. In MRF Transport Type, choose the transport type to use for the MRF INVITE request.
  6. Enter the the FQDN of the MRF in Mrffqdn.
  7. Click Save.

To create an MRF with the Routing Type of IP Address V4 or V6:

  1. Select the MRF Routing Type as IP Address V4 or V6.

  2. Enter one or more (comma-separated) IP addresses for the MRF in Mrf IP Address. 
  3. In the MRF TG Name drop-down menu, choose the trunk group to use for MRF signaling.
  4. In Mrf Request URI, enter the Request URI to be sent in the MRF INVITE request.
  5. Enter the MRF Port number for the MRF server.
  6. In MRF Transport Type, choose the transport type to use for the MRF INVITE request.
  7. Click Save.
Note:

If you later need to edit or delete an MRF cluster, first set its State to Disabled. Set the State back to Enabled after you edit an MRF cluster.
