Add third party (Intercall) teleconference line through API

To add a new Teleconference line through the WebEx UI, you go to 'Preferences->Audio' then click on the 'Add account' link.

This opens up the following window where you can add a new teleconferencing account:

Can anyone tell my what the equivalent call would be in the web api?  I thought it might be in the 'SetUser', but nothing I have tried there has worked (https://developer.cisco.com/media/webex-xml-api/schemas/index.html?url=/media/webex-xml-api/schemas/user_xsd.html).  Guidance on this would be appreciated, thanks!

Does anyone have an idea of where I can access this through the webex API?

For anyone else having this issue, you need to set the tspAccount in the setUser call.

The toll and toll-free call in numbers also need to be formatted like this for the call to work:  1,123,456-7890

It may be helpful to add a conference line through the web ui first, then issue a getUser call to see the exact format everything needs to be in for the setUser call.
