Webex Calling API for provisioning cloud connected PSTN

[gary391]

Hi Team, 

I am looking for a webex API, that can allow enabling cloud connected PSTN option for a location, selecting the PSTN provider,

I just found this as I was trying to do exactly what the OP was asking and in 2025 it is now possible with the API's.

What I did was manually configure a location with the desired CCP. Then use the Get "Retrieve PSTN Connection for a Location" API to establish that those CCP settings were.

You can then use the Put "Setup PSTN Connection for a Location" and use Response data from the above as the Request Body.

One thing to remember is the location needs to be enabled for Calling for this to work. If you go into Control Hub/Location/Calling and see the "Set up Calling" button then the above will fail.

There is a "Enable a Location for Webex Calling" Post API that you can run first, however for whatever reason the site address details are mandatory for this. What I did was create the location and enable calling in a single step, then assigned the CCP. This is fine if you are looking to bulk add location and configure with CCP all in one go.

Hope this helps someone else!

Thanks for your patience @gary391 !
As far as I know, as of now there is no REST API available to enabling the Cloud Connect PSTN as of now.
This is the Help documentation though for this setup which you might be already aware of - https://help.webex.com/en-us/article/nw3ygtq/Cloud-Connected-PSTN

I'm currently checking with our internal Calling Engg. group if there is any plan to include it through API. Will let you know.
