Welcome to the RingCentral Community

Hi Tyler,

My understanding is that extension ID is only an internal identifier for the extension and cannot be remapped. Is that correct? We have multiple entities and these identifiers must be consistent across them (some employees provide services to more than one company). So for my use case, the value must be designated by us rather than RingCentral.

Passing this value by SAML would be great, since we use SSO into our RingCentral instance and it may help automate the process. I realize this may not be possible however.

Not sure if partnerID will get us what we want either. Upon review of the documentation, the API will only return account and extension IDs (again, I believe are exclusively internal RingCentral identifiers).

Unsure of how to proceed.

Thanks!

I believe RingCentral extension ID is similar to employee ID. But not exactly the same thing because each employee could have multiple extensions. I am wondering: how do you handle the case that multiple employees share the same phone? Then there is no way to tell which employee it is for from call log.
