Clustered Call Pickup provides Dialed Call Pickup functionality across a network or cluster.
The host switches
must have Release 7.0 software or later.
must all be part of the same Portable Directory Number (PDN) cluster.
must be directly connected by using IP trunking.
The cluster elements must be programmed with a Feature DN in the Cluster Element Assignment form.
The System Data Synchronization (SDS) feature must be sharing data between the host switches.
Remote members must be accessed via trunks that use DPNSS signaling (T1/E1 DPNSS, XNET, or IP trunks). Access via QSIG signaling is not supported.
If the host switches are not fully meshed with XNET IP signaling or some links are down, calls will not be picked up between switches without IP connectivity. The requesting switch will consider those systems that it cannot communicate with as having no ringing members in pickup groups.
Pickup groups can include members from a maximum of eight different cluster elements (including resilient backups).
RADs and embedded voice mail ports should not be included in Call Pickup groups.
A clustered call pickup group must include at least one local member.
If RDN Synchronization is supported in the cluster, you can add, delete, or change (renumber) directory numbers that are members of cluster call pickup groups from the User Configuration form.
If OPS Manager is used in your cluster to manage the element telephone directories, then you must use the OPS Manager Moves, Adds, and Changes (MAC) application to add, delete, or change (renumber) directory numbers that are members of cluster call pickup groups. Do not use the User Configuration, Single-Line Assignment, Multiline Assignment, or Wireless Set Assignment forms in the System Administration Tool to change a directory number that is a remote member of a cluster call pickup group if OPS Manager is managing the cluster telephone directories.
To change the directory number of that device that is a cluster call pickup group member using OPS Manager:
Delete the member from the clustered call pickup group from OPS MAC or through the Pickup Group Assignment form or Change Attribute Assignment form of the element's System Administration Tool.
Change (renumber) the directory number from the OPS Manager Moves, Adds, and Changes application.
Perform an OPS Manager synchronization to distribute the change to the cluster elements
Add the directory number to the clustered call pickup group through OPS MAC or to the call pickup group on the local element.
SDS then distributes the member to the other cluster elements that host that call pickup group.
If you change a directory number without first removing the member from clustered pickup group, and then perform an OPS Manager synchronization, the remote elements that host the clustered call pickup group will not be updated with the change by the OPS Manager synchronization. An OPS Manager synch error "delta" is generated on OPS Manager to alert you that the change was not made on the remote elements.
To correct:
Log into the element identified in the error log.
Remove the member from the clustered call pickup group.
SDS removes the member from the remote cluster elements.
Perform a synchronization operation from OPS Manager to distribute the remote directory number updates to the cluster elements.
Add the renumbered remote member back into the clustered pickup group of the local element.
SDS updates the remote elements that host the clustered call pickup group with the member.
Clustered Pickup Groups do not display in the Group Administration Tool.
Also refer to the Dialed Call Pickup Conditions.
To program Clustered Call Pickup:
Ensure that the System Data Synchronization (SDS) feature is sharing data between the cluster elements. Review the SDS guidelines that relate to clustered call pickup groups.
Complete the programming for Dialed Call Pickup.
In the Pickup Group Assignment form, set "Cluster Enabled" to "Yes".
Add local, resilient, and remote members to the pickup group.
Note: When you add a new Pickup Group or change a group from the Add or Change dialog box, the system suggests the next available Pickup Group ID. Because other groups likely exist on other controllers in the network, the next available group ID may not be the next number.
