Call a Finn and you may not hear "hello" at all. You'll often hear a name, and sometimes just the surname: Lahtinen. That's the whole greeting, and it counts as the efficient way to answer — the caller now knows they got the right person, and no words were wasted.
The other thing to know is at the end. Finnish has a goodbye that exists nowhere except on the phone: kuulemiin, roughly "until we hear each other." Say it on the street and you'll get a strange look.
Answering and Saying Who You Are
Hello?
Haloo?
Lahtinen speaking.
Lahtinen.
Hi, Mikko here.
Hei, Mikko tässä.
It's me.
Minä täällä.
Who's calling?
Kuka siellä?
Library, good afternoon.
Kirjasto, hyvää päivää.
Sorry, who am I speaking to?
Anteeksi, kenen kanssa puhun?

Haloo?
Tässä or täällä, both mean "here": Mikko tässä and Mikko täällä are equally normal for introducing yourself, and which one a Finn uses is habit rather than rule. You'll also hear the surname put first in the genitive — Korhosen Sari tässä, "the Korhonens' Sari here" — an old way of placing a person that's dialect-flavoured and rural rather than neutral. Recognise it; don't copy it into a business call.

Voinko puhua Sari Korhosen kanssa?
Business calls go plural: at work you'll hear the polite plural instead of sinä — Odottakaa hetki, "wait a moment," where the plural ending is the politeness. Finnish doesn't bolt a "please" on the end; if you want one, it's Pieni hetki, kiitos. Customer service is one of the few places in modern Finland where the formal form survives in daily use, and the same softening works on your own requests: voisitko rather than voitko to someone you don't know.
When the Line Is Bad
Can you hear me?
Kuuluuko?
I can't hear you.
En kuule sinua.
I have bad reception.
Minulla on huono kuuluvuus.
Could you repeat that?
Voitko toistaa?
Could you speak louder?
Voitko puhua kovempaa?
The call cut out.
Puhelu katkesi.
I'll call you back in a moment.
Soitan sinulle kohta takaisin.

Kuuluuko?
One word, one question: kuuluuko? is literally "is it audible?" and it's the whole phrase. Finnish does this a lot — a single verb in the right form replaces the English sentence, and on a bad line that's exactly what you want.
Numbers, Wrong Numbers and Hanging Up
What's your phone number?
Mikä on puhelinnumerosi?
I think I called the wrong number.
Taisin soittaa väärään numeroon.
Wrong number.
Väärä numero.
Thanks for calling.
Kiitos soitosta.
Goodbye. (on the phone)
Kuulemiin!
Let's talk again!
Soitellaan!

Say it slowly: a Finn may read a number out digit by digit or group the digits in twos and threes, and which you get is unpredictable — so you need the tens as well as the units, all in Finnish numbers. Asking someone to slow down is the same voitko toistaa? from the table above.
Texting Instead
I'll send you a message.
Laitan sinulle viestiä.
Send me a text.
Lähetä minulle tekstiviesti.
Shall I call or send a message?
Soitanko vai laitanko viestiä?
Call me when you have time.
Soita kun ehdit.
I'll be in touch.
Otan yhteyttä.

Laitan sinulle viestiä.
Message first, call second: this is the part of Finnish phone culture most worth absorbing. An unannounced call to someone you don't know well is mildly intrusive, and a text asking voinko soittaa? before you ring is normal adult behaviour rather than excessive caution. Work calls are different and get picked up immediately. The vocabulary for all of it — viesti, puhelu, videopuhelu — is in technology and internet words.
How a Finnish Call Actually Goes
It is shorter than you expect. The surname answer, your own name, the thing you rang about, a decision, kuulemiin. There's no warm-up, no "how are you," no narrating the weather — the ritual phase of a phone call that exists in many cultures has been removed, and what's left is business. If you've read about Finnish small talk, none of this will surprise you; the phone just concentrates it.
The one place that economy breaks down is with friends and family, where calls ramble like anywhere else and often end with soitellaan — "let's call each other sometime," meaning roughly as much as it does in English.
A practical note: if you need an answer, text. If you're leaving a message with a human, give your name and number twice and slowly — soittakaa takaisin numeroon… — because Finnish phone numbers read aloud at speed are hard for everyone.
And a word on haloo. It does two jobs: it's a perfectly normal way to answer informally or when you don't recognise the number, and it's also what you say when you can't tell whether anyone's still on the line — the same slightly irritated hello? English uses. With friends you'll also get moi, terve or just noni. The everyday greetings for every other situation are in greetings and goodbyes.
