Hello, we want to be able to track our incoming calls with our different marketing channels. When we set up the account we asked that we have a different number set up for each that way we can track the origin of each call. So they set it up but it doesnt seem to work with our IVR system. How can we make this work?For example, we have a phone number we put on our yard signs and when they call it will come up on the caller ID as "yard Signs" but if we set it to go to the IVR it loses this name.
