With financial support from Sanders and Hubbard, Bell hired Thomas Watson as his assistant,[N 15] and the two of them experimented with acoustic telegraphy. On June 2, 1875, Watson accidentally plucked one of the reeds and Bell, at the receiving end of the wire, heard the overtones of the reed; overtones that would be necessary for transmitting speech. That demonstrated to Bell that only one reed or armature was necessary, not multiple reeds. This led to the "gallows" sound-powered telephone, which could transmit indistinct, voice-like sounds, but not clear speech.
What name was given to the telephone that sort of worked?
gallows

In 2008, Dahabshiil Group acquired a majority stake in Somtel Network, a Hargeisa-based telecommunications firm specialising in high speed broadband, mobile internet, LTE services, mobile money transfer and mobile phone services. The acquisition provided Dahabshiil with the necessary platform for a subsequent expansion into mobile banking, a growth industry in the regional banking sector. In 2014, Somalia's three largest telecommunication operators, Hormuud Telecom, NationLink and Somtel, also signed an interconnection agreement. The cooperative deal will see the firms establish the Somali Telecommunication Company (STC), which will allow their mobile clients to communicate across the three networks.
