Call forwarding from one extension to another extension within my company

We are having a problem forwarding calls from one extension to another extension. In this case we want to be able to forward calls from a manager to an assistant, both with their own separate extensions. This would also preferably be done through the RC mobile app since this can mobile at all times. Apparently there is no way to do this currently, even with RC support.

I have the same problem. there is no error code just no option to enter an extension but just the direct number.

Are you using the "/forward" API? If so, I found out that the API reference is missing the option to specify the extension number. See this working function in Node JS

async function forwardCall(call, toExtensionNumber, toPhoneNumber){
var endpoint = '/restapi/v1.0/account/~/telephony/sessions/[telephonySessionId]/parties/[partiesId]/forward'
    var resp = await, {
      extensionNumber : toExtensionNumber // NOT EXTENSION ID!
    var jsonObj = await resp.json()

If you forward to a phone number, that phone number must be online with one of the device (like RingCentral Phone app or a hard phone).

What was the problem when you transfer a call to another extension? Any error code or error message?
