TWO DIFFERENT PLIVO PRODUCTS

Know which Plivo product you are comparing

didlogic is a carrier that operates its own network: 12 physical PoPs, its own Autonomous System (AS13006), and SIP trunks and numbers provisioned in the portal or through the API, with no per-trunk or per-channel fee. Its counterpart at Plivo is Zentrunk, Plivo’s SIP trunking, which connects a PBX, SBC, or AI platform to the phone network.

Voice API and Voice AI Agents are a different layer, so they are not compared here. If you plan to run a PBX, an SBC, or an external AI platform, the carrier layer is the one to compare.

Compare didlogic with Plivo SIP trunking on one route group, with the same calls on both sides.

Two layers of a voice setup: call logic on top, carrier layer below. This page compares didlogic with Plivo at the carrier layer.

START WITH THE WORKLOAD

Which one fits your stack?

Both connect SIP traffic to the phone network. didlogic adds its own network and international coverage; choose by where your call logic runs and which countries you need numbers and routes in.

Where didlogic is the stronger choice

Plivo would only be the carrier: the dialer or AI platform on top stays as it is.
You need numbers or routes outside the US and India, without moving to an Enterprise plan.
Outbound calls need caller ID from numbers you hold with another provider.
Bursty outbound traffic needs more than 1 to 2 CPS.
You want a carrier that operates its own network, with 12 physical PoPs and its own AS, and an engineer answering tickets 24/7.

Where Plivo is a good fit

Your numbers and traffic are in the US or India.
Your app runs on Plivo’s Voice API, Audio Streaming, or Voice AI Agents.
You want voice, SMS, WhatsApp, and Verify from one provider.

WHERE TO START

Good workloads to test first

International outbound

Destinations outside the US and India. Compare per-route rates, call completion, and caller ID on one destination group.

AI voice agents

If Vapi, Retell, LiveKit, or your own stack runs the agent, point one market’s SIP trunk at didlogic and compare the same calls.

Numbers held elsewhere

Outbound caller ID from numbers you keep with another provider. Test CLI passthrough on one route.

Bursty dialer traffic

Campaigns that start calls faster than 1 to 2 CPS. Set the test trunk to your real peak.

The didlogic network, in numbers

didlogic operates AS13006 across 12 physical PoPs, with direct Tier 1 connectivity and SIP provisioning through the portal or API. Evaluate routing and call quality using your own traffic.

CALLS PER SECOND

Check capacity before a dialer or AI workload goes live

On didlogic

CPS and concurrent channels are raised on request for the trunk that carries your test. Outbound channels are set by account level: 5, 50, or unlimited.

On Plivo SIP Trunking

Each trunk starts at 1 CPS, drawn from an account pool of 1 to 2 CPS on US plans. Concurrency runs from 5 to 50 by plan and spend. Calls over a limit are rejected, not queued.

AI agents and dialers start calls in bursts. Bring your real peak CPS so both sides are tested at the rate you will actually run.

Cost model comparison: Plivo bills outbound minutes by destination, monthly number fees and a short-call surcharge, and coverage beyond the US and India sits on the Enterprise tier from $1,000 a month; didlogic bills minutes per route and country, number rental by country, and raises CPS on request.

TEST BEFORE YOU DECIDE

Test on your own traffic before you commit

Whether you are choosing your first provider or adding a second one, start with one market, route group, or AI agent. Expand only if the result justifies it.

Test didlogic

Step 1

Add a didlogic test connection

Claim a free test number once your business account is reviewed, add a test trunk, set authentication and caller ID, and agree the destinations to test.
Step 2

Route a representative sample

Use one market, one route group, one AI agent, or a controlled share of outbound traffic.
Step 3

Measure both on the same calls

Measure call completion, post-dial delay, caller-ID presentation, audio, DTMF or transfers, billing increments, and unit cost on comparable traffic.
Step 4

Expand only if it earns it

Add routes, markets, or numbers only after the technical and commercial result is clear. Porting stays a separate decision.

CUSTOMER STORY

Outbound calls to Iraq, back at a 60%+ ASR

Zain’s network-level filtering had flagged the client’s caller IDs, and outbound calls to Iraqi leads stopped connecting. didlogic rebuilt the lane with dedicated termination routes, caller IDs validated against live completion data, and a standing rotation process that retires numbers before they degrade, bringing answer seizure ratio back to a sustained 60%+.
