Five conversations that decide whether a customer stays

Financial services teams do not make one kind of call. Onboarding, service, advice, arrears, and claims each carry a different obligation and a different consequence when the call does not connect. didlogic carries all of them on one account.

Onboarding and identity verification

A verification callback that goes unanswered stalls an application. Place outbound verification and welcome calls on a local number in the applicant’s own country, so the call arrives as a number their handset does not treat as foreign. HLR lookups via API confirm a mobile number is live, valid, roaming, or ported before your system dials, which catches transposed digits at the application stage rather than at the callback stage.

Customer service lines

Publish a local, national, or toll-free number for each market and each brand, and point all of them at the contact center platform, PBX, or call group you already run over standard SIP. One account, one balance, every market. Toll-free lines remove the cost barrier on the number printed on cards and statements.

Advisory, dealing, and relationship calls

Where a conversation can lead to a transaction, the recording is part of the record rather than a nice-to-have. The lines that need recording get it, the ones that do not, do not, and the setting sits per SIP account or per number.

Collections, arrears, and payment reminders

Contact rate is the whole problem in collections. Run reminder and arrears campaigns from your dialer or an AI voice agent on local caller ID per market, with answering machine detection so agents connect to people rather than voicemail, and high-CPS routes so a predictive dialer runs at the pace it was tuned for.

Claims, renewals, and servicing follow-up

First notice of loss, renewal calls, and servicing follow-ups should arrive from the same number the customer already has saved from the original relationship. Hold one consistent caller ID per market across the lifecycle so a follow-up call reads as continuity rather than a cold approach.

What financial services teams check before signing a carrier

Procurement in this sector asks a narrower set of questions than most. Can we present the right number in every market we operate in, is the audio path controlled, can we produce the recording when someone asks for it, and how long does the vendor review take.

Get numbers for verification and support calls across 140+ countries. Outbound caller ID availability depends on the call origin, destination, and route.

Encryption on signaling and audio
Encryption on signaling and audio

TLS encrypts SIP signaling. Optional SRTP encrypts the audio stream itself, and didlogic supports SRTP on inbound DID numbers as well as the outbound leg, which many providers do not. Operations are certified to ISO/IEC 27001:2022 and EN ISO 9001:2015 by TÜV AUSTRIA.

Recordings your archive can ingest

Recording enabled per SIP account or per number, each file mapped to its CDR by Call ID, with a webhook the moment it is ready. You keep the audio in your own retention system.

Numbers you keep
Numbers you keep

Eligible numbers port to didlogic and keep working throughout the transfer. The number on the back of the card, on the policy document, and in the customer’s contacts does not change.

Uptime the queue depends on
Uptime the queue depends on

Termination is homed to in-country carriers on our own network and monitored 24/7, with failover that reroutes traffic before calls drop. A service line going quiet is a reportable incident, not an inconvenience.

No lock-in on the layer underneath
No lock-in on the layer underneath

Standard SIP into your contact center platform, PBX, 3CX or Asterisk build, dialer, or AI voice agent. Change platform above the trunk without changing carrier, and take your numbers with you if you ever leave.

The carrier layer, not another platform to migrate to

didlogic is not a core banking system, a CRM, a contact center suite, or a compliance archive. We supply what those systems cannot: phone numbers in the countries you operate in, SIP connectivity to the public phone network, carrier routing, call recordings, and the call detail records your reporting and reconciliation run on.

Connect over standard SIP from your contact center platform, hosted or self-built PBX, predictive dialer, or AI voice agent. Numbers activate through the portal or API. When you enter a new market or restructure a business line, only the numbers and routes change. Everything above them stays put.

The carrier layer, not another platform to migrate to

Which number belongs on which line

Four number types, one billing model: monthly rental plus a per-minute rate on inbound calls. The right pick depends on what the line is for and how you want to appear on a customer’s screen.

Local

Tied to a city or area code. The choice for outbound: verification callbacks, arrears calls, and relationship calls where the customer sees a number from their own city.

Mobile

Mobile-range numbers, available where supported. Useful in markets where customers screen unfamiliar landline numbers and answer mobile-format numbers first.

Toll-free

Free for the caller, reverse-billed to you. The default for a published support or fraud line, where removing the cost barrier matters more than local flavor and the number goes on cards, statements, and policy documents.

National

One non-geographic number for a whole country. Fits a single servicing line per market, and holds up when branch structure changes underneath it.

VIRTUAL NUMBERS

Local numbers in the markets you operate in

Monthly rental per number plus per-minute inbound rates, published per country and number type before you buy. Outbound is billed per destination. Search any country in the pricing table.

Can an offshore contact center present a UK caller ID?

It depends on where the call originates, the number presented, and the route used. If your team calls UK customers from abroad, check whether the route supports the UK number you want customers to see.

UK landline numbers. Since 29 January 2025, Ofcom expects providers to block calls arriving from abroad that falsely display a UK landline number. The guidance allows limited exceptions for legitimate calls. Ofcom’s landline guidance. ofcom.org.uk

UK mobile numbers. Ofcom published updated guidance on 15 July 2026. It takes effect on 15 July 2027. Under that guidance, providers should withhold the caller ID on calls that appear to come from a UK mobile roaming abroad unless they can verify the number. The call can still reach the customer with the number withheld. Ofcom’s caller ID guidance and effective dates. ofcom.org.uk

Tell us where your agents call from and which UK number you want to display. Our engineers will check caller ID availability for your route before you start calling customers.

Check caller ID availability

We own the network the call runs on

Own network

We operate our own Autonomous System and own the hardware in all 12 points of presence. Customer calls do not detour through a third-party cloud on the way to the phone network.

Direct in-country routes

Calls terminate through local carriers, taking the shortest domestic path. That is what holds audio quality on a call where a customer is reading out details, and answer rates on a campaign where every unanswered call is a cost.

Engineers, not ticket queues

A servicing line that stops ringing cannot wait for a next-business-day reply. Reach engineers over chat and email when a route needs attention.

One portal, separated access

Numbers, trunks, CDRs, recordings, and billing in one place, with role-based access so each business line, brand, or regional team sees only its own numbers. Auto top-up with backup card rules means a declined card never takes a customer line offline.

How call recordings reach your compliance archive

Enable recording on selected SIP accounts or phone numbers. didlogic matches each recording to its call detail record (CDR) by Call ID. When the audio file is ready, didlogic sends a webhook so your system can retrieve the recording and store it in your archive alongside the matching call record.

What didlogic provides

  • Recording controls for each SIP account or phone number.
  • A CDR at call end with the Call ID, phone number, call direction, and timestamp.
  • A webhook when the recording is ready for retrieval.
  • TLS for SIP signaling and optional SRTP for audio in transit.

What your firm manages

  • Decide which conversations to record and which lines to enable.
  • Establish the lawful basis for recording and notify customers as required.
  • Set retention periods and configure archive storage to prevent alteration or premature deletion.
  • Control and log access, supervise recorded calls, and retrieve records for review.

Frequently asked questions

What does a financial services company need from a voice carrier?

Four things, consistently: phone numbers in every market where it holds customers, caller ID presentation that survives the receiving network’s checks, encryption on signaling and audio, and call recordings that can be tied to a specific call and handed to a retention system. didlogic supplies local, national, mobile, and toll-free numbers in 140+ countries, TLS with optional SRTP, and recordings mapped to each call detail record by Call ID.

Why do banks and insurers use local numbers in each market instead of one international line?

Calls presented with a local caller ID are generally more likely to be answered than calls from unfamiliar foreign or withheld numbers, which matters most on verification callbacks, arrears calls, and renewal contact where an unanswered call has a direct cost. A local inbound number also gives customers a familiar, low-cost way to reach the institution. didlogic provides local numbers in 140+ countries.

Can a firm present a UK caller ID when calling from an offshore contact center?

Only in limited circumstances. Ofcom’s CLI guidance sets out that UK providers are expected to identify and block calls arriving from outside the UK that present a UK number as the Presentation Number, apart from a limited set of legitimate use cases, and Ofcom published a decision in July 2026 extending the approach to UK mobile numbers. The practical route for a financial firm is to originate the call in-country, on numbers held in its own account, through a provider licensed in that market. didlogic offers in-country SIP trunking and Licensed Local Voice Service in selected jurisdictions including the United Kingdom.

Does didlogic provide MiFID II compliant call recording?

didlogic supplies the recording, not the compliance programme. We record the carrier leg per SIP account or per number, map each file to its call detail record by Call ID, and notify your systems by webhook the moment a recording is ready. Retention periods, non-erasable storage, access traceability, supervision, and scoping remain the firm’s obligations under Article 16(7) of MiFID II and Article 76 of Delegated Regulation (EU) 2017/565. No carrier can discharge those on your behalf.

Are calls through didlogic encrypted?

Yes, encryption is available. TLS protects SIP signaling, and optional SRTP encrypts the audio stream itself, so third parties cannot read or tamper with the call in transit. didlogic supports SRTP on inbound DID numbers as well as outbound calls. Operations are certified to ISO/IEC 27001:2022 and EN ISO 9001:2015 by TÜV AUSTRIA. See the encrypted calls page for supported platforms.

Does didlogic replace a contact center platform or core system?

No. didlogic is the carrier layer underneath them. Your contact center suite, CRM, dialer, or core system keeps handling queues, cases, records, and workflow, while didlogic supplies the phone numbers, SIP routes, recordings, and call records they run on.

How fast can a financial institution get numbers in a new country?

Same day for most destinations, activated in real time through the self-service portal or API. Compliance documents are verified automatically in about 5 minutes. Countries with local registration requirements take longer, and the didlogic team manages the documentation to keep timelines short.

Can an institution keep its existing customer service numbers?

Yes. Eligible numbers can be ported to didlogic and keep working throughout the transfer, so the numbers printed on cards, statements, and policy documents do not change. Timelines depend on the country and the current provider.

Can AI voice agents handle payment reminders and account servicing calls?

Yes. Teams connect AI voice agents built on platforms like Vapi, Retell, ElevenLabs, or LiveKit to didlogic over SIP, then run reminder and servicing lines on local numbers in each market. Answering machine detection keeps the agent off voicemail. What the agent is permitted to say, disclose, or collect remains governed by your own conduct rules. See the AI voice page for how the connection works.

Can phone numbers be validated before an outbound campaign?

Yes. HLR lookups via API check in real time whether a mobile number is active, valid, roaming, or ported. Teams use this at application intake and before arrears or renewal campaigns to catch mistyped numbers and drop dead records, which cuts failed attempts and wasted agent time.

What does voice cost for a financial services organization?

Numbers are billed as a monthly rental plus a per-minute rate on inbound calls, with exact figures published per country and number type on the phone number pricing page. Outbound calls are billed per destination at the rates on the call rates page. Everything is prepaid from one account balance.

Which countries does didlogic cover?

didlogic provides local, national, mobile, and toll-free numbers in 140+ countries, including markets that are difficult to source elsewhere. The phone number pricing page carries the full list with live pricing.
