For a remote office with only internet connectivity, Cloud-Connected PSTN is the standard and most reliable model. It routes all calls (including emergency calls) over the internet to the Webex cloud, which then connects to the PSTN, eliminating the need for any on-premises PSTN hardware at that location.

The most efficient first step in Control Hub is to verify the device’s fundamental configuration. Ensuring it is correctly assigned to the proper user and location confirms it is receiving the right provisioning files and service entitlements, which is a common root cause for registration failures.

Before you can port numbers, you must first define the Telephony Service Provider (TSP) in Control Hub. This entity represents the carrier from whom you are porting the numbers. Creating the TSP is a prerequisite step for submitting a porting order.

The most scalable and administratively clean method is to use Locations and Class of Service (CoS) templates. You would create a CoS template that blocks international calls and assign it to a ‘Sales’ Location. You would create another CoS template that permits international calls and assign it to a ‘Management’ Location. Users are then moved to the appropriate Location to inherit the correct policy.

The ‘Maximum Wait Time’ setting defines how long a call will remain in the hunt group queue, ringing available agents, before it is redirected based on the ‘No Answer Destination’ policy. Setting this to 20 seconds achieves the described behavior before sending the call to the informational voicemail.

The ‘Reports > Historical Reports’ section is specifically designed for generating detailed, customizable reports on calling activity. It allows you to select date ranges, filter by users/locations, and choose data points like call duration, cost, and destination, making it ideal for billing and usage analysis.

When adding agents (users) to a hunt group, you can expand their entry and selectively choose which of their devices receive hunt group calls. You would deselect their desk phone and mobile device, selecting only their ‘Webex App’ or similar softclient device type to achieve the desired ring behavior.

While a Location contains an emergency address, its primary administrative purpose is as a policy container. It groups users and devices to uniformly apply settings like Class of Service (calling permissions), PSTN connection type (Cloud-Connected or Local Gateway), and local dialing rules, simplifying large-scale management.

The correct workflow is: First, port or purchase numbers to add them to your organization’s number inventory (2). Next, numbers are inherently associated with a specific Location’s PSTN configuration (3). Finally, you can assign an available number from that Location’s pool to an individual user (1).
