A computerized system and related method for assisting a user with placing a telephonic call, comprising a user interface, computerized processing, and computerized storage for: a user specifying an originally-specified telephone number to place an intended telephonic call, which telephone number, as originally-specified, for at least one particular reason, cannot be used to successfully complete the intended telephonic call; the user, after specifying the originally-specified telephone number, later specifying later-specified telephone number elements, including the possible deleting or ignoring of part of the originally-specified telephone number; and causing the telephonic call to be successfully signaled using the originally-specified telephone number in combination with the later-specified telephone number elements, without the user having to re-specify the originally-specified telephone number.
