New features

CRM / Helpdesk Integration Template
  • Added support for integrating Yeastar P-Series PBX System with a CRM / Helpdesk system via custom integration template.

    If your desired CRM / Helpdesk is not in the list of ready-made integrations provided by Yeastar, you can implement a custom integration by creating a CRM / Helpdesk integration template to integrate Yeastar P-Series PBX System with a CRM / Helpdesk system that supports REST API.

    For more information, see Custom CRM Integration Guide and Custom Helpdesk Integration Guide.

    • Manage custom integration templates that you have added or uploaded.
LDAP Server Integration
Added support for the integration with a third-party LDAP server, which allows for automatically triggering contact lookup in your LDAP server when an inbound call reaches your PBX and displaying caller's name if a match is found. In addition, contact synchronization with phonebook(s) enables convenient outbound calling from Linkus UC Clients and intelligent inbound call routing based on phonebook(s) matches.
For more information, see LDAP Server Integration Guide.
