I cannot imagine anyone calling 'Mogadisco Centre 'along the way either.
Mogadishu information, 11300, 5567 is based in the large United Nations compound of Gigiri, on the outskirts of Nairobi. This is the ICAO headquarters for this region. Been in there myself in person although years ago. Most of the controllers there were Rwandan and they act as the caretaker of Somalia. Thank goodness for HF, they can sit 560nm from Mogadishu and control the airspace.
Strange enough, these airways are quite busy, when you consider a lot of these airports have limited parking space, flights are co-ordinated not to overlap if parking is an issue. Therefore aircraft stream in at intervals through the day and night on these airways. Remember Reunion island uses these airways too, with a lot of French traffic, Air France, Air Austral, Corsair etc...
