Telephony, VoIP & SMS

Telephony, VoIP and DID — beside WhatsApp, not replaced by it.

Connect your PBX, SIP provider, DID ranges and SMS gateway — or use ours where you would rather not manage it. Both run in the same queues, with the same reporting.

An estimate for planning, not a quote. Per-minute and number rates vary by destination and carrier — if you bring your own SIP trunk or DIDs, confirm them with your provider. Inbound minutes are usually free or near-free. Excludes the whtapis platform fee and taxes.

Three ways to get voice in

Mix them freely. One queue can take a WhatsApp voice call, a PBX call and a call on a Spanish DID in the same minute.

Path 01

WhatsApp only

Voice and messaging entirely on the WhatsApp Business Platform. No carrier contract, no trunk, no hardware.

One number and one identity per market

Nothing to procure from a telco

Ideal where voice minutes are expensive

Fastest to launch

Path 02

WhatsApp + classic telephony

Your PBX and PSTN lines stay exactly where they are. We front both channels with one queue and one wallboard.

SIP trunk or direct PBX bridge

Existing extensions and hardware phones keep working

Published numbers stay published

Lowest disruption

Path 03

WhatsApp + VoIP / DID

Connect your own SIP provider and DID ranges, with least-cost routing between carriers and WhatsApp.

Any standards-based SIP provider

Per-country DID and toll-free ranges

Your negotiated rates, unchanged

Most control

Bring your own

Your VoIP account and your SMS gateway, under our routing.

If you have negotiated rates, you keep them. Point the trunk at us and the platform treats those channels as its own, least-cost routing included.

If you would rather not deal with carriers at all, we provide numbers, minutes and SMS in the markets we cover.

Your SIP trunk

Credentials, IP authentication or registration, with codec and DTMF negotiation handled.

Your DID ranges

Import existing numbers, assign them to queues, campaigns or agents.

Your SMS gateway

Keep your provider and rates; the platform sends through your account and reports on it.

Your PBX

Bridge to Asterisk, FreePBX, Avaya, Cisco or a hosted PBX over SIP.

Ours instead

Numbers, minutes and SMS provided by us in the markets we cover, on one invoice.

Numbering, routing and cost control

Least-cost routing

Per destination and per time of day, across WhatsApp voice, your trunks and ours.

Number presentation

Set the outbound caller ID per campaign, market or agent, within local rules.

Inbound number plans

Map DIDs, toll-free numbers and WhatsApp numbers to queues and schedules.

Failover

Automatic carrier failover with alerting when a trunk degrades.

Fraud controls

Destination allow-lists, spend ceilings and anomaly alerts on outbound traffic.

Cost reporting

Minutes, messages and segments by channel, country, queue and campaign.

Interoperability

Tested against the equipment you probably already have.

Standards-based SIP. These are the platforms our onboarding teams see most often.

Carrier and numbering work

Someone has to own the trunk.

Bringing your own carrier means SIP credentials, DID ranges and least-cost routing rules. Our team does that part with your telecom owner.
