Overview

How Dollu serves contact centres & bpo.

Contact centres and BPOs sell outcomes - answered calls, resolved tickets, completed sales - and telecom is the largest variable cost standing between them and margin. Dollu was built for this traffic. Our switching core absorbs predictive-dialler bursts of thousands of calls per second, our Premium tier delivers CLI to the handset so calls are not flagged as spam, and our per-destination rate decks and 1/1 billing mean you pay for what connects. Whether you run collections into the US, sales into the UK or support back into India, the routes are direct.

Inbound is just as important. We provision toll-free numbers, geographic DIDs and mobile numbers in more than 100 countries, handle porting and local regulatory documentation on your behalf, and route inbound calls to any SIP endpoint, cloud platform or agent, anywhere. Numbers can be added per client and per campaign through the portal or API, so onboarding a new account in a new market takes days rather than months and every number sits on the same invoice as your outbound minutes.

Around the voice layer we offer the tools an operator needs: a cloud contact centre with omnichannel routing, IVR and conversational AI, SIP trunks into Genesys, Avaya, Five9, Amazon Connect or your own dialler, quality monitoring with per-campaign ASR and MOS, and fraud protection against PBX hijack and traffic pumping. For distributed workforces we add zero-trust access, SD-WAN and dedicated internet so home agents sound like floor agents. All of it is monitored by a 24×7 NOC with fifteen-minute P1 response.

Challenges

What keeps communications and network teams up at night.

  • Answer rates and CLI presentation

    Predictive diallers push thousands of calls per second, and every point of answer-seizure ratio is revenue. Grey routes strip or rewrite CLI, calls get labelled as spam and campaigns underperform for reasons that are invisible from inside the dialler.

  • Multi-country inbound presence

    Clients expect a local number in every market they sell into - toll-free in the US, geographic in the UK, mobile in Brazil - often provisioned in days, with porting, address proof and regulatory paperwork handled on their behalf.

  • Margins under constant pressure

    Per-minute costs, idle channel capacity, seat licences and telecom overheads compete with wage inflation. Operators need transparent per-destination pricing, 1/1 billing increments and the freedom to choose a different quality tier per campaign.

  • Distributed and hybrid workforces

    Home-based agents mean voice quality depends on residential broadband, security teams worry about data leakage, and clients still expect the same recording, monitoring and PCI controls they would get from a physical floor.

Solutions

Each solution maps to specific Dollu services - click through for full detail, specifications and FAQs.

  • Dialler-ready outbound termination

    Direct A–Z routes with Premium CLI-guaranteed, Standard and Wholesale tiers selectable per campaign, high CPS and channel limits, STIR/SHAKEN attestation for US traffic and real-time ASR/ACD/PDD dashboards to tune the routing mix.

  • Inbound numbers wherever your clients sell

    Toll-free, geographic and mobile numbers in 100+ countries with porting handled end to end, flexible routing to SIP or PSTN endpoints, and per-client sub-accounts so each engagement has its own numbers, CDRs and invoice lines.

  • Cloud contact centre and SIP trunking

    A multi-tenant CCaaS with skills-based routing, IVR, conversational AI and omnichannel queues, or elastic SIP trunks into the platform you already run - bursting to thousands of channels for seasonal campaigns without hardware.

  • Compliance and fraud controls

    Real-time detection of PBX compromise, IRSF and traffic pumping, per-trunk velocity and destination limits, TCPA and DNC-aware calling windows, and security assessments of your agent desktop and network estate.

  • Secure agent connectivity

    Zero-trust access for home and gig agents, SD-WAN and dedicated internet for delivery centres, and QoS-marked voice paths so calls sound the same whether the agent sits in Noida, Manila or their kitchen.

FAQ

Contact Centres & BPO - common questions.

The questions customers and carriers ask us most often before they interconnect. If yours is not here, our team answers within one business day.

Still have a question?

Ask our solutions team

Yes. Dialler traffic - high calls per second, short average call duration, low ASR by design - is a large share of what we carry. We set CPS and concurrent-channel limits per trunk to match your dialler profile, and our routing engine is tuned so bursts do not trigger false fraud blocks or degrade other customers.
