Use of telephone interconnect on a portable or mobile radio usually requires a lot of ergonomic inter- action. If the telephone call that the user places is busy because the phone on the other end is in use, it can be inconvenient for the radio user to constantly redial the phone line in an attempt to place the call. What would be convenient is to have a mechanism which will moni- tor the status of the phone line (by constantly redialing on its own) and alert the radio user when the phone call gets through.
