Webex Calling PSTN options and selection

Verified 2026-09-15 · 25 sources · tier 2 · 2 disputed

Also known as CCP, CCPP, Cisco PSTN, Outbound Calling Plan, Regional Media for CCP, premises-based PSTN.

Disputed: 2 sources below carry conflicting evidence.

Webex Calling provides 3 PSTN connectivity options: Cisco Calling Plan, Cloud Connected PSTN from a partner provider, and premises-based PSTN through a Local Gateway 7. Exactly 1 PSTN choice can be configured for each Webex Calling location 5.

How PSTN selection operates

The PSTN provider handling a call is determined solely by the originating location of the Webex Calling call 6. No other call attribute influences PSTN selection, including the called number 6.

An organisation may combine different PSTN types across its locations, such as assigning Cisco Calling Plan to 1 location, Cloud Connected PSTN to a second, and Local Gateway to a third 4. Cloud PSTN, covering both Cisco Calling Plan and Cloud Connected PSTN, provides PSTN access exclusively for Webex Calling users; premises users cannot route calls to cloud PSTN through that path 2.

Cisco Calling Plan

Enabling access to Cisco Calling Plans requires purchasing at least 1 committed Outbound Calling Plan licence 19. Orders for standard phone numbers have a ceiling of 100 numbers per order, requiring separate orders for additional quantities 16. Numbers may be ordered individually or as a Block Order in increments of 10, 50, or 100 8. Numbers ordered inside a block are indivisible: an individual number cannot be deleted, and removing part of a block requires deleting the entire block and placing new orders 8.

In the field, the Cisco Calling Plans documentation is structured across 19 country tabs covering the United States, Belgium, Canada, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Lithuania, Luxembourg, Netherlands, Poland, Sweden, Switzerland, United Kingdom, Australia, and New Zealand, with each tab detailing requirements and limitations 9. In the field, 18 of those 19 tabs state that Cisco Calling Plans are not supported with Webex Contact Center or authorized for use with high-concurrent calls, high-volume calls, or uncommonly short or long calls, and the United States tab is the sole exception 12. The United States tab states that Cisco Calling Plans supports Webex Contact Center only through the use of Service Numbers 25. 18 of the 19 country tabs state that Cisco Calling Plans aren't supported with Webex Contact Center nor authorized for use in which high-concurrent calls or high-volume calls or uncommonly short or long calls are made 1.

In the field, toll-free availability is split across 3 distinct positions in the country tabs: the United States tab states that toll-free numbers are restricted to U.S. and Canada locations, 17 tabs state that toll-free numbers are not currently available for new orders or ports, and the Canada tab makes neither statement 24.

When configuring a Cisco PSTN connection for the first time at a location, the required Emergency Service Address disclaimer must be signed by a customer administrator account; Cisco does not permit partner administrators or cross-launched customer administrators to sign it 13. If emergency service address validation fails during setup for a premises-based or Cisco Calling Plan connection, an administrator may close the address screen and proceed 14. Cisco states that an unvalidated address may delay emergency call handling and incur additional charges if calls route to an emergency relay centre 14.

Cloud Connected PSTN

Cloud Connected PSTN (CCP) providers operate either as integrated or non-integrated partners 17. Integrated providers deliver numbers directly into Control Hub for unified procurement and provisioning, whereas non-integrated providers require numbers to be procured externally and manually entered into Control Hub 17.

In the Control Hub partner list, partners displayed with a logo provide Regional Media for Cloud Connected PSTN 20. For partners listed as a text string followed by a bracketed region, administrators must select the region nearest to the location's country to use Regional Media 20. Regional Media routes PSTN traffic through a local data centre when the provider connects to the local region, falling back to the organisation's home region when it does not 22. Regional Media does not apply to Webex room systems 22. Regional Media is documented for Webex Calling for Service Providers and Webex Calling for Value Added Resellers across 5 regions combined in 1 port reference table: U.S., Canada, EMEA, Australia, and Japan 23. In the field, the Regional Media documentation expands the initialism CCP as Cisco Calling Plan within its body, despite Cloud Connected PSTN being the subject defined in its title and opening sentence 21.

PSTN migrations and transitions

Sources disagree on whether an existing location can adopt the Cisco Calling Plan 11​15. This is disputed: when adding a location, Cisco states that the Cisco PSTN option is visible only if at least 1 committed Cisco Calling Plan Outbound Calling Plan has been purchased, the location is in a supported country, the organisation is hosted in a supported Webex Calling data centre region, and the location is new, because pre-existing locations that have had other PSTN capabilities assigned aren't eligible for the Cisco Calling Plan 11. This is disputed: elsewhere, the organisation configuration article documents changing the PSTN connection of an existing location to Cisco PSTN, naming premises-based Local Gateway locations and non-integrated Cloud Connected PSTN locations as the starting points, and gives an 11-step Control Hub procedure for it 15.

Cisco lists 3 migration exclusions where changing a location's connection to Cisco PSTN is unsupported: the Japan region, a location integrated with IntelePeer, and a Dedicated Instance location 10. During a PSTN connection transition, number management is frozen: numbers cannot be added, deleted, moved in, or moved out, though existing numbers remain functional and can be assigned or unassigned 18.

Applicability

Applies to: Cisco Webex Calling. Deployments: multi-tenant. Sources checked 2026-09-15. Regional Media is documented as available for Webex Calling for Service Providers and for Webex Calling for Value Added Resellers, over 5 regions combined into 1 port reference table: U.S., Canada, EMEA, Australia and Japan 23. Transitioning an existing location to Cisco PSTN excludes the Japan region 10.

What remains uncertain

Sources disagree on whether a pre-existing location that has had other PSTN capabilities assigned can change to the Cisco Calling Plan or is ineligible because only new locations can take it 11​15.

The Supported paths for PSTN migration table inside the Cisco Calling Plans article is not covered by the sources below.
