Interactive voice response (IVR) systems are meant to make customer calls more efficient—but sometimes they get in the way.
For the last five years, it has been possible to initiate outgoing calls via Voximplant cloud without specifying a source phone number. Such feature was provided mainly for new developers, and if an optional caller id was not specified, the special “fallback” number was used automatically. However, the telecom landscape has changed so far, and now many telecom operators drop such calls, which results in unwanted side-effects for the “call without a caller id” feature.
