What does dialling mean?
Dialling refers to the act of entering a telephone number to make a call, as in dialling directory enquiries or dialling an overseas number from abroad. It also carries an older, more specialized sense: the craft of constructing sundials and marking out their hour lines, a discipline known as gnomonics that was prized as a branch of applied geometry before clocks became widespread. Spelled with a double L in British English but with a single L (dialing) in American English, the word derives from 'dial', which traces back through Medieval Latin dialis to Latin dies, meaning day — fitting, since early dials were instruments for reading the sun's daily course. Today the telephone sense dominates everyday speech, though touchscreen phones mean many people now 'tap' rather than dial, giving the word a faintly nostalgic ring. Its most familiar fixed uses include direct dialling, international dialling codes, and the dialling tone heard on landlines.
The act of entering a telephone number to place a call; also, historically, the art of constructing sundials.

In British English spelled 'dialling'; American English uses 'dialing'.
Present participle and gerund of the verb 'dial': to operate a dial or press digits to connect a telephone call.
"He was still dialling when she picked up the receiver."
Functions as the continuous form of 'to dial'; the doubled-L spelling is British.
Before telephones existed, 'dialling' meant something far more mathematical: designing and positioning sundials, an art so precise it was once considered a branch of geometry.

Etymology of dialling
Dialling comes from 'dial', which entered Middle English around the fifteenth century from Anglo-French and Medieval Latin dialis, ultimately deriving from Latin dies, 'day'. The earliest sense related to timekeeping devices that tracked the sun's daily path, hence the specialized noun meaning the design or construction of such dials. With the invention of the rotary telephone in the late nineteenth century, the verb 'to dial' was coined from the circular finger-plate on early phones, and 'dialling' followed as both its gerund and a standalone noun for the act of placing a call. Words sharing the dies root include diary, diurnal, and journal, all carrying the notion of a day.

How dialling is actually used
'Dialling' follows British doubling conventions after a stressed final syllable ending in vowel + l; American English writes 'dialing'. As a noun in its sundial sense, the word is technical and now rare, belonging mainly to horological and gnomonic literature. In everyday use it almost always refers to telephone calls, though even there digital touchscreens have made the phrase feel slightly dated.
Easily confused with dialling
'Dialling' with double L is the standard British spelling, while 'dialing' with one L is the American variant — same word, different conventions.
