The Private Network Connect (PNC) feature allows Webex Calling customers to extend their private network to the cloud. This is done through either partner cloud or direct connects to ensure high quality of service and low latency for voice calls, provide network security and provide overall improved call experience for end users.
Benefits provided by PNC include:
-
Enables service providers (SP)s to bundle their networks with Webex Calling.
-
Offers large enterprises the ability to integrate directly to Webex Calling.
-
Automates and streamlines the process for provisioning customer VLAN access to Webex Calling.
-
PNC is available to SP and Value Added Reseller (VAR) partners and is ordered for customers through the Cisco Commerce Workspace (CCW). Once ordered in CCW, the feature is visible and configurable within Control Hub.
-
PNC must be used in conjunction with an IP Interconnect to a Webex Calling data center.
 | PNC provides access to Webex Calling workloads. Other Webex workloads and network services (Meetings, Messaging, DNS, Control Hub, etc.) are accessed Over The Top (OTT) Internet. |
IP Interconnect options and specifications are as follows:
Partner-level Interconnect
The Partner (SP or VAR) is responsible for establishing an IP interconnect directly to a Webex Calling data center. This model is used by partners that aggregate Virtual Private Networks (VPNs) or Private IP Networks from multiple customers within a single direct connect. Each customer is provisioned on a Virtual Local Area Network (VLAN) with a contracted amount of bandwidth. A partner can establish direct connects to multiple Webex Calling data centers globally.
Customer-level Interconnect
Direct Connect—A direct connection is used for a single customer and the customer can establish direct connects to multiple Webex Calling data centers globally. The entire bandwidth of this interconnection is available and dedicated to that particular customer.
The partner or the system administrator are able to configure the VPN server for each IP Interconnect that the partner or customer has enabled. The settings per IP Interconnect include:
-
VLAN ID
-
Speed
-
BGP
-
ASN
-
IP address of Webex Calling Interface
-
IP address of customer interface
-
Subnet
| If you're a customer administrator managing the PNC on a Partner Interconnect, coordinate any changes with your partner prior to entering in Control Hub to avoid any potential network connectivity issues. |
Once you’ve selected the type of interconnect that you use, you can enable PNC for a location in Control Hub.
Partners and administrators who have editing permissions can enable a Private Network Connect (PNC) location.
If the interconnect you want to use is on a router that is in maintenance, you can't create the VLAN.
Before you begin
Ensure to complete these tasks before creating a VLAN, and enabling your location for Private Network Connect (PNC):
-
Partner or customer interconnect established
-
PNC licenses ordered in CCW.

PNC can't be enabled for a customer until a VLAN has been created.
All VLANs should be configured before changing the connection type.
Whether enabling or disabling PNC for a location, once the process starts you can view the progress on the Tasks page.

What to do next
Once the process of enabling/disabling PNC is shown as completed on the Manage Tasks page in Control Hub, endpoints will require attention:
-
Phones will need to be resynced. You can resync the phones from Control Hub or have the users resync their phones from the phone settings menu.
-
Users will need to log out and back into mobile & desktop clients.
-
Customer-managed devices will need to have their Outbound proxy (OBP) updated in the configuration files. See Add your customer managed device for more information.
-
Locations using Premise based PSTN will need to reconfigure the Trunks on each local gateway with the new OBP. See information on Managing Premise Based PSTN.
