CallThru SIX

The Phone System Built Inside Your Collections Software, Not Bolted On

Most dialers talk to your collection software through batch files and overnight imports. CallThru SIX doesn’t. It’s built directly on top of DebtMaster, reading and writing account data in real time. When a debtor pays five minutes before a scheduled call, CallThru SIX already knows. When a call ends, the result is on the account before the collector hangs up. No sync delay. No stale data. No compliance gap.

Real-Time Connectivity

Real-Time, Not Batch

Most dialers in the collections industry run as separate systems, syncing to your collection software on a schedule. That delay creates real risk. An account flagged for an outbound call can already be resolved by the time the dialer reaches it, and your collector software won’t know until the next batch import runs. CallThru SIX eliminates the gap. It feeds outbound campaigns directly from DebtMaster in real time, picking up account changes as they happen. If a debtor calls in and pays before their scheduled call, CallThru SIX recognizes the update and the call doesn’t happen. When a call completes, the result is written back to the account immediately, available to the collector on the very next screen refresh, not the next morning’s import. For an industry where compliance depends on knowing the current state of an account before you dial it, real-time beats batch every time.

Compliance Rules That Adapt to You

Every collection agency carries its own risk tolerance, its own footprint of states and provinces, and its own internal policies. CallThru Six is built to flex with all of it. Maintain your own do-not-call lists inside the platform. Set no-contact state rules specific to your agency. Manage Reg F's 7-in-7 call frequency limits without manual tracking. Agencies operating across both the U.S. and Canada can apply the correct compliance logic to each region automatically.

Your Own DNC Lists

Maintain agency-specific do-not-call lists inside CallThru Six, updated in real time. No batch imports, no manual list uploads, no lag between when a number is flagged and when the platform respects it.

No-Contact State Rules

Configure calling restrictions by state or province, specific to your agency's footprint. Set different rules for different regions so your team stays compliant without checking a manual reference before every call.

Reg F Frequency Management

Manage the 7-in-7 call frequency limits required under Regulation F without manual tracking or spreadsheet workarounds. CallThru Six monitors call attempts per contact window and enforces the limit automatically.

Jurisdiction-Aware Logic

Agencies operating across the U.S. and Canada can apply the correct compliance logic to each region automatically. Rules are configurable by jurisdiction so the right logic applies to every account, every time.

Power & Pace Dialing

Dial Faster, Reach More Accounts

CallThru SIX’s Power Dialing puts push-button calling directly in the Collector, Account, and Client windows, reducing misdials and getting agents to the next call faster than manual dialing ever could. Pace Dialing takes it further, automatically dialing the right number as each account loads in a worklist, so agents spend their time talking, not dialing. Both respect your compliance settings automatically. No-contact states, calling time windows, and do-not-call rules are checked before every call, whether it’s dialed manually or automatically.

Everything Your Phone System Should Do, In One Platform

Real-Time Sync

CallThru SIX pulls account data straight from DebtMaster in real time. Payments, promises, and account changes reflect immediately, so agents never work from stale information.

AI Voice Engine

CallThru SIX’s AI Voice Engine replaces static, pre-recorded prompts with real-time, natural-sounding text-to-speech, generated from live account data. Greetings, IVR menus, and outbound messages can include the debtor’s name, balance, or due date — spoken clearly and naturally, without a studio recording session. Update your message scripts whenever you need to, with no re-recording required.

Power Dialing

Push-button calling lives directly in the Collector, Account, and Client windows. Fewer misdials, faster time to the next call.

Pace Dialing

The system dials the next number automatically as each account loads. Agents spend their time talking, not dialing.

Compliance Management

Do-not-call lists, state-specific no-contact rules, and Reg F's 7-in-7 limits are all managed inside the platform. U.S. and Canadian rules apply automatically based on where the account sits.

Call Recording

Every call is recorded and linked to the right account automatically. No separate system to manage, and access is controlled by permission level.

Private Deployment

Your call data lives in your own private database, not a shared cloud environment. It's your history to query, analyze, and build on.

Your Calls. Your Database. Your Advantage.

Every call CallThru SIX makes or receives becomes structured data, automatically linked to the right debtor account in DebtMaster. The call duration, the collector on the line, the number dialed or the caller ID captured — it’s all there the moment the call ends, visible right alongside collector notes on the same account screen.

Call Records

Every inbound and outbound call logs automatically, with timestamps, disposition codes, and outcomes tied to the account record. No manual entry required.

Real-time posting means supervisors can see what's happening across the floor as it happens — not after a batch sync the next morning.

Call Recordings

Recordings stay attached to the account for as long as you need them, with access limited to the roles you define.

Your Database

Years of call data build up in your own database over time, ready for reporting or AI-driven analysis whenever you need it.

Predictable Pricing. No Surprises.

Many dialer platforms in the collections space bill by the connected minute, which means your phone costs swing month to month based on call volume. CallThru Six runs on private deployment with flat, predictable monthly pricing instead. You know what you're paying before the month starts, not after the invoice arrives. No shared cloud infrastructure, no variable per-minute surprises, and no dependency on someone else's multi-tenant system to keep your calls running.

Flat Monthly Rate

One consistent monthly cost regardless of call volume. Budget with confidence and stop absorbing phone bill surprises at invoice time.

Private Deployment

Your calls run on dedicated infrastructure, not shared cloud. No multi-tenant congestion, no third-party dependencies, and no performance variation based on what other accounts on the platform are doing.

No Per-Minute Billing

Per-minute billing turns your dialing productivity against your budget. The harder your team works, the higher the bill. CallThru Six removes that tension entirely.
