Feedback?Harness Cloud PSTN for effortless Webex Calling solution
Cisco has partnered with Tata Communications Limited (TCL) to offer cloud PSTN services as a Cloud Connected PSTN Provider (CCPP) for organizations operating in India. Consequently, Webex Calling customers with offices only in India have the option to utilize cloud-based PSTN from Tata Communication Ltd in addition to on-premises PSTN through a Local Gateway.
For Webex Calling customers in India who are not using "Webex Calling by Tata Communications", see Enable Webex Calling for India locations.
Benefits
Using a CCPP in India offers the following benefits:
-
It simplifies the process of provisioning and managing PSTN services, which in turn enables you to save on hardware purchases and management.
-
It facilitates quick and seamless deployment of Webex Calling services. Once the partner PSTN is configured in the Control Hub, numbers can be added and assigned to Webex Calling users.
-
A single service provider partner handles calling licenses, cloud PSTN, network and managed services. This simplifies support and compliance with India telecom regulations.

-
Webex Calling users in India should be entitled for a calling license, which can be either a standard or a premium license. These calling licenses and the PSTN should be obtained from Tata Communications.

Toll bypass support
Webex Calling supports toll bypass policies that apply to both Sell-In customers and MNC customers with branch offices in India under this offer. Customer administrators are responsible for configuring Webex Calling locations in India to ensure compliance with toll bypass regulatory requirements.
Limitations
The following limitations apply in India:
-
Attempts to call a PSTN number or receive a call from a PSTN number, when the user is roaming to a different enterprise location than their assigned enterprise location isn’t currently supported.
-
For organizations using a centralized VPN, users appear to connect from the VPN gateway’s network location. As a result, the system cannot determine the users' actual geographic locations, causing toll bypass policies to be applied inaccurately.
-
Ensure to set the Call routing between Webex Calling and on-premises to
Standard. This setting is the accurate toll bypass policy for inbound calls routing if an organization has Webex Calling locations in India. -
A Webex Room Device that is not registered directly with Webex Calling is considered to be outside the enterprise network, so roaming policies apply.
-
The endpoints with IPv6 addresses are not supported.
-
To route calls from Webex Calling user to on-premises users on Cisco Unified Communication Manager (UCM), use the enterprise dial plan to match patterns on Unified CM.
-
Customers who want to retain media on their local network need to configure ICE-Lite on the Cisco Unified Border Element (CUBE). For details, see ICE-Lite Support on CUBE.
-
Partner recording solutions like Dubber aren’t supported (Webex recording is supported).
-
Sending and receiving Fax from a device that uses the T.38 protocol isn't supported.
Internet Telephony Numbers for Webex Calling in India
In India, Department of Telecom (DOT) assigns special numbers known as Internet Telephony Numbers (ITN) or mobile numbers to PSTN providers. Organizations with these numbers can access Webex Calling services through the internet. Additionally, Webex Calling users in India who are assigned with these numbers are exempted from toll bypass regulations as long as they remain within India.
"Webex Calling by Tata Communications” supports Internet Telephony Numbers (ITNs). Customers should procure ITNs directly from Tata Communications Limited and assign these numbers to users, features, workspace devices, and virtual lines, just as they would with standard fixed-line numbers. ITNs are 10-digit numbers beginning with '9'. In Webex Calling locations within India, customers may use a mix of standard fixed-line numbers and ITNs, or create locations using only ITNs. For locations with both number types, Zone and Trusted Network Edge must be configured as they would for standard fixed-line numbers. If a location uses only ITNs, Zone and Trusted Network Edge configuration is still required, but no subnets need to be specified in Zone and Trusted Network Edge. For details, see Internet Telephony Numbers for Webex Calling in India.
