Business Communication Solutions with the UCM6300 IP PBX Series by Grandstream 

When setting up an effective business communication system, customization becomes essential for efficiency and flexibility. A local VoIP system offers vast capabilities, allowing companies to design scalable solutions tailored to their needs. One of the key benefits of VoIP systems is the ability to create call centers, enabling businesses to enhance customer experience. 

The UCM6300 series by Grandstream offers a comprehensive suite of call center features, helping businesses efficiently and effectively run their operations. 

 

Call Queues 

Call queues are a fundamental component of any call center, consisting of callers, agents, distribution strategies, and hold music. When calls are received, they are placed in a queue and then distributed to agents based on a predefined strategy. Distribution strategies include: 

  • Ring All: The system rings all available agents simultaneously until one answers. 

  • Linear: Calls are assigned to agents in a predefined order. 

  • Least Calls Received: The call is directed to the agent who has received the fewest calls recently. 

  • Fewest Completed Calls: The system routes the call to the agent who has completed the fewest calls. 

  • Random Selection: The call is transferred to a randomly chosen agent. 

  • Round Robin: Calls are distributed in a rotating manner among agents. 

The UCM6300 IP PBX series by Grandstream also supports virtual queues, where customers can request a callback instead of waiting on hold. The system then automatically calls them back when their turn arrives, enhancing customer satisfaction. 

 

Monitoring and Supervision 

The UCM6300 series by Grandstream offers advanced monitoring features, enabling supervisors to provide immediate support to agents. These features include: 

  • Listen: The supervisor can listen to the call without being heard by either party. 

  • Whisper: The supervisor can talk to the agent without the customer hearing. 

  • Barge: The supervisor can join the call and speak with both parties. 

Additionally, the UCM6300 IP PBX series by Grandstream provides comprehensive call queue statistics, helping supervisors assess agent performance and analyze call data such as login/logout times, call distribution, and missed calls. This contributes to improving daily call center operations. 

 

Computer-Telephony Integration (CTI) 

The integration between telephony and computers (CTI) allows agents to manage calls easily via their computers. The UCM6300 series by Grandstream provides the GS Affinity interface and a web-based dashboard for monitoring call queues and executing various functions, such as: 

  • Viewing waiting and active calls 

  • Changing agent status 

  • Managing active calls effortlessly 

Supervisors can also access an advanced control panel for more detailed call center management. 

 

Customer Relationship Management (CRM) Integration 

The UCM6300 series integrates with CRM systems such as Zoho CRM, SugarCRM, and Salesforce, enabling agents to access caller information and provide a more personalized customer experience. 

 

Interactive Voice Response (IVR) and Call Recording 

The UCM6300 series by Grandstream features a built-in IVR system, allowing businesses to create a hierarchical call routing structure with up to five levels. Settings can be customized to include welcome messages, keypad-driven menu selections, and blacklist/whitelist management. 

Additionally, the UCM6300 IP PBX series supports both automatic and manual call recording, enabling companies to maintain call logs for evaluation, training, and performance analysis.
