Acabamos de usar el teléfono de incidencias.

It means to have just done something.

So acabamos de usar = we have just used / we just used.

This is a very common Spanish structure:

• Acabo de comer = I’ve just eaten
• Acaban de llegar = They’ve just arrived

It is formed with:

• acabar in the present tense
• de
• an infinitive

So here:

• acabamos = we finish / we are finishing, but in this structure it helps mean we have just
• de usar = to use

Together: we have just used.

Because in Spanish, acabar de + infinitive uses the present tense to express something that happened very recently.

So even though the action is in the past, Spanish says:

• Acabamos de usar... = We’ve just used...

This is different from English, where learners often expect a past form. In Spanish, this present-tense pattern is the normal way to say just did.

Because acabar needs de in this expression.

The fixed pattern is:

• acabar de + infinitive

So you say:

• acabo de llamar
• acabas de salir
• acabamos de usar

You cannot say acabamos usar in standard Spanish.

Because after acabar de, Spanish uses the infinitive.

That is the normal structure:

• acabar de comer
• acabar de llegar
• acabar de usar

So usar stays in its dictionary form, meaning to use.

Acabamos means we just...

It is the nosotros form of acabar.

Full verb pattern:

• yo acabo
• tú acabas
• él/ella/usted acaba
• nosotros/nosotras acabamos
• vosotros/vosotras acabáis
• ellos/ellas/ustedes acaban

Spanish often leaves out the subject pronoun, so nosotros is not needed. The verb ending -amos already tells you it means we.

In Spain, incidencia often means an issue, problem, fault, incident, or service problem, depending on context.

So el teléfono de incidencias is not literally just any phone related to incidents. It usually means something like:

• the problems helpline
• the fault-reporting phone number
• the customer service line for issues
• the incidents/issues line

In practical terms, it is the number or phone service you use to report a problem.

This de is different from the one in acabamos de usar.

Here, de links two nouns and shows a relationship, similar to:

• phone for issues
• issues phone line
• incident-reporting phone

Spanish often uses de where English uses noun-noun combinations:

• teléfono de emergencias = emergency phone / emergency line
• centro de salud = health centre
• tarjeta de crédito = credit card

So teléfono de incidencias literally looks like phone of issues, but naturally it means phone line for reporting issues/problems.

Spanish often uses the definite article more than English does.

So usar el teléfono de incidencias is completely natural and usually preferred when referring to a specific, known service or line.

Compare:

• Usamos el teléfono de incidencias = We used the issue-reporting phone line
• Usamos un teléfono = We used a phone

Here, el suggests a specific phone line that both speaker and listener can identify.

Yes, but the meaning is slightly different.

• Acabamos de usar el teléfono de incidencias = We just used the issues phone line
• Hemos usado el teléfono de incidencias = We have used the issues phone line

Acabamos de usar strongly emphasizes that it happened a moment ago.

Hemos usado says the action has happened, but does not focus as clearly on the idea of just now.

So if the meaning is very recent, acabamos de usar is the better choice.

Yes, llamar could also be natural, depending on the intended meaning.

• Acabamos de usar el teléfono de incidencias = We just used the issues phone line
• Acabamos de llamar al teléfono de incidencias = We just called the issues number/helpline

The original sentence focuses on using the phone line/service.
With llamar, the focus is specifically on making a call.

In many contexts, llamar al teléfono de incidencias may sound even more precise.

They can overlap, but incidencias often sounds a bit more formal, technical, or administrative in Spain.

• problemas = problems
• incidencias = issues, faults, incidents, service disruptions, reported problems

For example, companies, buildings, internet providers, schools, and public services often talk about incidencias when referring to things that need reporting or fixing.

So teléfono de incidencias sounds like the kind of label you might see in official or service-related contexts.

A simple pronunciation guide would be:

ah-kah-BA-mos deh oo-SAR el teh-LEH-fo-no deh een-thee-DEN-thee-as

In much of Spain, c before e/i is pronounced like the th in think, so:

• incidencias sounds roughly like een-thee-DEN-thee-as

In Latin American Spanish, it would more likely sound like:

• een-see-DEN-see-as

Both are correct for their regions, but for Spain the th sound is typical.

Not really.

A very literal breakdown is:

• Acabamos de = we just...
• usar = use
• el teléfono de incidencias = the issues phone / incident phone

But natural English would usually say something like:

• We just used the helpline for reporting issues
• We just called the fault-reporting line
• We’ve just used the incidents/issues phone line

So the Spanish makes perfect sense word-for-word, but natural English usually needs a smoother phrasing.
