Compare telecoms and VoIP quotes in Dublin

Dublin's telecoms market has eir Business, Vodafone Ireland, and Three Ireland as the main infrastructure players, alongside the full range of international UCaaS providers - RingCentral, Vonage, Zoom Phone - who have established a significant presence as multinationals have moved their European headquarters to Dublin. Many Dublin businesses are still on ISDN (BRI or PRI), which eir is migrating away from. The practical urgency is comparable to the UK's PSTN switch-off: plan the migration before you are forced into it under a deadline. ComReg governs the market, and EU Electronic Communications Code protections apply. RFXapp collects competing bids so you can compare what providers actually include.

If you are looking for the best providers in Dublin, the most reliable shortlist is one built around your own requirements and tested with a structured brief - not a generic ranked list. RFXapp helps you find and collect quotes from the right suppliers, and analyse them so you can compare what they actually offer, not just the headline price.

What to consider before you go to market

Getting comparable quotes starts with a well-scoped brief. These are the things most businesses overlook until they're already in the process.

ISDN and PSTN migration: plan proactively

eir has been migrating businesses off PSTN and ISDN to fibre and VoIP. Ireland's migration timeline is less coordinated than the UK's December 2025 switch-off date - it has been rolling and premises-specific rather than market-wide. Many Dublin businesses, particularly those in older IFSC or city-centre buildings, are still on ISDN BRI or PRI circuits. The practical urgency is the same as the UK switch-off: once eir gives a discontinuation notice for your circuit, you are migrating under a deadline rather than on your own terms. Plan the migration now to control the timeline and the commercial terms.

Hosted VoIP vs SIP trunking vs on-premise

These three architectures have different cost profiles, reliability characteristics, and administrative overhead. Hosted VoIP is the right choice for most Dublin SMEs. SIP trunks suit businesses that already have a PBX they want to retain - common in older ISDN-era setups in Dublin. On-premise is rarely appropriate for a new deployment unless there is a specific security or compliance requirement. Know which model you are buying before briefing providers, or you will receive quotes that are impossible to compare.

Number porting under ComReg rules

Number porting in Ireland is governed by ComReg's number portability framework, which is aligned with the EU Electronic Communications Code. Simple business ports typically complete in 1-5 business days. Complex porting of DDI ranges or geographic number blocks takes longer, particularly where eir is the losing carrier. Port failures and delays occur in the Irish market as elsewhere - ask every provider to describe their porting process and what compensation applies if a port fails.

EU Electronic Communications Code protections

Ireland has transposed the EU Electronic Communications Code (EECC) into Irish law. This provides Dublin businesses with contract transparency obligations, switching rights, and consumer protection provisions that are broadly comparable to the Ofcom framework in the UK. Providers operating in Ireland are required to give clear pre-contract information on pricing, contract duration, and exit rights. If a provider's contract documentation is unclear or incomplete on any of these points, that is both a commercial and a regulatory flag.

Contract length and early termination charges

Telecoms contracts in Ireland typically run 12-24 months, with early termination charges calculated as the remaining monthly fees. On an €600/month contract with 18 months remaining, the ETCs are €10,800. Read the ETC clause carefully and calculate the maximum liability before signing - particularly in Dublin where businesses relocate, restructure, or change headcount frequently, and where multinationals can have contract terms that do not align with their Irish subsidiary's actual needs.

Integration with Microsoft Teams and CRM platforms

Dublin's multinational and professional services sector runs heavily on Microsoft Teams, Salesforce, and HubSpot. VoIP systems that integrate natively with your existing tools reduce friction and improve call logging. Ask every provider to confirm which integrations are in the standard package versus charged as add-ons - this is particularly relevant in Dublin where providers quote to both SMEs and multinational subsidiaries with different integration expectations.

Contract traps that catch Dublin businesses out

These are the clauses and assumptions that make two telecoms quotes look comparable on paper but several thousand euros apart once you're locked in.

Migrating under an eir discontinuation deadline

Dublin businesses that wait for an eir ISDN or PSTN discontinuation notice before starting their VoIP migration typically end up on worse contract terms than those who plan proactively. A provider who knows you have a hard deadline has less incentive to compete on price or offer flexible terms. The 30-90 day notice windows that eir typically gives for circuit discontinuation are not long enough to run a proper competitive procurement. Start the process now, on your own timeline, and maintain competitive tension throughout.

Early termination charges on 12-24 month contracts

An Irish telecoms ETC is one of the highest-value contract traps for Dublin businesses. A business on a 24-month contract at €700/month that wants to leave at month 10 faces ETCs of €9,800. This is discovered most commonly when Dublin offices relocate, when a multinational subsidiary's contract scope changes, or when a better deal becomes available. Calculate the maximum ETC liability before signing.

"Unlimited calls" with fair use policies that cap peak usage

Unlimited call packages from eir Business, Vodafone Ireland, and Three Ireland all carry fair use policies that define what "unlimited" actually means. Common restrictions include limits on calls to certain number ranges (international destinations, premium-rate numbers), limits on concurrent calls, and restrictions on call-centre-style usage. Two "unlimited" packages at similar monthly prices can cover very different actual usage patterns. Read the fair use policy before comparing headline prices.

Questions that separate good providers from great ones

Asking is only half the job. Below each question is what a good answer looks like, and what should give you pause. Questions marked * are mainly relevant for larger or more complex deployments.

"Walk us through how you manage a number port from eir - what's the typical timeline and what happens if it fails?"
Why ask it: Porting numbers away from eir in Ireland has historically been one of the more complex domestic porting scenarios in the Irish market. A provider with direct eir porting experience in Dublin will understand the specific process and realistic timelines; one without that experience may be optimistic.

Good answer: A specific description of the ComReg number portability process for eir migrations, how they communicate progress, the typical Dublin timeline for business DDIs, and what they do if a port fails or is delayed - including compensation.

Red flag: "Porting is normally straightforward." Every provider has had porting problems. This answer means they have no visible process for handling failures.
"What does your out-of-hours support look like - specifically, who do we call if our phones are down at 8am on a Monday?"
Why ask it: This tests whether "24/7 support" is a staffed operation or a voicemail-to-ticket system. For a Dublin business where phones are a primary communication channel, the practical reality of out-of-hours support matters considerably.

Good answer: A specific phone number for out-of-hours emergencies, a named team or on-call rota, a response time commitment in writing, and an explanation of what SLA credits apply if the response time is missed.

Red flag: "You'd log a ticket through the portal." A ticketing system is not out-of-hours support for a business with no working phones.
"What is the early termination charge if we need to exit the contract at 12 months?"
Why ask it: Irish telecoms contracts typically calculate ETCs as the full remaining monthly fees. Asking for the specific figure gives you a concrete euro amount to evaluate rather than a clause to read later.

Good answer: A specific € figure, calculated clearly, with an explanation of whether there are any contractual mechanisms - such as a premises change clause - that reduce the ETC.

Red flag: Vagueness about the calculation method, or a redirect to "we can discuss that if it comes up."
"Which integrations are included in the base price - specifically, does Microsoft Teams or Salesforce cost extra?"
Why ask it: Integration pricing is one of the most common sources of post-signature cost surprises in VoIP. Features listed in the sales presentation as capabilities may be billable add-ons in the actual contract.

Good answer: A clear, written breakdown of what is in the base package and what is charged separately - with specific reference to the integrations you use, confirmed in the quote document rather than verbally.

Red flag: "Most integrations are included" without specifics. That hedge means some are not, and you will find out which ones when the bill arrives.
"What broadband speed and quality do you recommend for our user count, and will you assess our current line before quoting?"
Why ask it: A VoIP system that degrades under load is worse than the ISDN it replaced. This question tests whether the provider is qualifying the fit between their system and your actual connectivity - particularly relevant in older Dublin buildings where broadband quality can be variable.

Good answer: A specific bandwidth recommendation based on your headcount and call concurrency assumptions, a willingness to assess your current connection quality before finalising the quote, and an honest answer about what happens if your broadband does not meet the required threshold.

Red flag: "Your current broadband should be fine." This means they have not checked and are assuming the sale rather than qualifying the fit.
"What fair use restrictions apply to your unlimited calls package - what are the concurrent call limits and which number ranges are excluded?"*
Why ask it: Unlimited call packages almost always carry restrictions on certain number ranges, concurrent call limits, and usage patterns. For a Dublin professional services or multinational subsidiary with high outbound call volumes, these restrictions can be the binding constraint on what the package actually covers.

Good answer: A specific description of which number ranges are excluded, concurrent call limits, and what happens when usage exceeds the fair use threshold - with the policy document available in writing.

Red flag: "We don't really have restrictions." Ask for the fair use policy in writing - every unlimited package has restrictions.

Where you have more negotiating room than you think

Telecoms providers have more flexibility on price and terms than they show in their initial quote. These are the levers that work once you have competing quotes in front of you.

5-12% savings

Multi-year commitment in exchange for a rate reduction

Providers will discount meaningfully for a longer commitment because the incremental revenue on a multi-year contract is high-margin for them. The trade-off is ETC liability. Before taking this deal, calculate the maximum ETC at the worst-case exit point and ask whether the provider will agree a capped ETC figure rather than a remaining-term calculation.

8-15% savings

Use international UCaaS provider quotes to pressure eir and Vodafone

RingCentral, Vonage, and Zoom Phone all operate in Ireland and price below eir Business and Vodafone Ireland at comparable functionality levels. Getting quotes from two international UCaaS providers and presenting them to your incumbent creates genuine commercial pressure. eir and Vodafone will typically improve their pricing rather than lose an established account.

5-10% savings

End-of-quarter timing

Telecoms providers in Ireland are target-driven and quarter-end produces better discounts than mid-quarter. Irish financial quarters typically close in March, June, September, and December. Aligning your decision with quarter-end and making clear you are comparing three providers simultaneously creates genuine urgency. Most effective when the contract is above €400/month.

3-8% savings

Competitive quotes shared with the incumbent

If you have an existing eir or Vodafone relationship, sharing competing quotes from independent UCaaS providers is one of the most reliable price levers available. Both incumbents will typically match or improve on a competing quote rather than lose an established account. Make sure quotes are genuinely comparable - same service scope, same contract length.

Prevents overruns

Negotiate the ETC cap before signing

Some providers will agree a capped exit fee rather than a full remaining-term calculation - for instance, capping ETCs at six months of fees regardless of when in the contract you exit. This is a legitimate negotiating point and some Dublin providers will accept it on contracts above €400/month. Ask before you sign - once the contract is executed, the clause is fixed.

Prevents overruns

Pre-agree the day rate for out-of-scope configuration work

Any VoIP migration from ISDN involves configuration tasks that turn out to be more complex than the initial scope assumed - legacy call flows that need replicating, custom IVR menus, integration setup with your CRM or Microsoft Teams, or connectivity issues with older Dublin office buildings. Without a pre-agreed rate for this work, each task gets priced at the moment of maximum inconvenience. Agree a named day rate for professional services work in the contract before signing.
