TARDIS telephone

A telephone capable of calling and receiving calls from anywhere in time and space was present in both of the Eleventh Doctor's TARDIS console rooms, as well as within the police box plasmic shell. When Jamie used Om-Com to call the police box phone, the Ninth Doctor said it wasn't possible — that phone was just a dummy. (TV: The Empty Child) The external phone was impossibly called again in the Doctor's eleventh incarnation, by Clara Oswald. (TV: The Bells of Saint John)

The Tenth Doctor's TARDIS was noticeably missing one, and the Doctor was forced to use the mobile Martha Jones gave him for all incoming and outgoing calls. (TV: The Sontaran Stratagem/The Poison Sky, The Stolen Earth) Following that console room's destruction and the TARDIS' "regeneration" into a new one, (TV: The Eleventh Hour) though, the Eleventh Doctor's TARDIS had one on the control console. Amy Pond was surprised to find it when Winston Churchill called; the Doctor replied, "It's a phone box." (TV: The Beast Below) In a psychic pollen-induced shared dream, Rory Williams suggested calling for help using the TARDIS phone as they approached a cold star. (TV: Amy's Choice) Just after Rory and Amy's wedding, the Doctor was informed by phone about an Egyptian goddess loose on the Orient Express, in space. (TV: The Big Bang) It was also through this telephone that the Doctor was informed of the Brigadier's death. (TV: The Wedding of River Song) This console phone had a cord long enough that its user could use it outside. (TV: Day of the Moon, WC: Pond Life) It also had an answering machine. (WC: Let's Kill Hitler Prequel, The Doctor, the Widow and the Wardrobe Prequel) The Doctor's next TARDIS also had a phone, and Vastra called it to tell him Clara Oswald satisfied the "one-word test" with the "pond". (TV: The Snowmen) The interior phone was rarely used, though, as, after Clara impossibly called him on the exterior police box phone, (TV: The Bells of Saint John) calls were directed to that phone instead. (TV: The Time of the Doctor) To call Kate Stewart, he was forced to hang outside of the TARDIS to reach it, as the TARDIS was in the air being transported by helicopter. (TV: The Day of the Doctor) Similarly, when Clara called him while he was orbiting Trenzalore with enemy ships surrounding him, he had to quickly reach out to get the phone. He gave Handles the command to remind him to patch the telephone back through the console unit to finally fix the problem, and this reminder ended up being Handles' final words before malfunctioning and "dying".
