Gunn's Rotary Phone

Gunn's Rotary Phone was a landline phone, and the first commercial telephone, invented by the Waterdhavian inventor Gertrude Gunnhilde. 
It consisted of a rotary dial, then a receiver and speaker which would be held in each hand (or propped up somewhere).
Since telephone cable was expensive for the local authority, it only saw use within big cities like Waterdeep, Hjarofjall and Fort Helena, for instance. Over cross-country, it was simply not viable to maintain the very delicate wire needed, so MacKenzie's Alternating Telegraph was used for those communications. However, it was a little cheaper to hook up to the grid compared to the telegraph.
== In Waterdeep ==
As with all good communication inventions, the Waterdeep Commercial Company was in charge of the phone lines of the city. 
Each district was assigned a short number code, and each address with a linked telephone would then have a short personal number. To ring up someone, you would call the operator and ask to be connected. The area codes were as follows, but you could just ask for the area, too.
District 	Code
Portico and Fort Mirror 	1
New Bristi 	2
The Narrows 	3
Dockward 	4
Clarkenwell 	5
Ironheath 	6
Edhellan 	7
Headland 	8
The Mills 	9
Northwards 	10
South Common and Fort Alderman	11
Fort Wheeler 	12
Waterdeep City Watch 	000
For example, you might ring up and ask for 'Clarkenwell 1921', please'.
