Both providers can support SIP workloads. The right choice depends on where your call logic runs, which services you need together, and whether a separate carrier makes sense for part of your traffic.
| Parameter | didlogic | Telnyx |
|---|---|---|
| SIP connectivity | SIP trunks for PBXs, contact centers, and AI voice platforms. | SIP trunks for PBXs and SIP-enabled applications. |
| Network & routing | Own ASN, 12 PoPs, and route-level options. | Own global network with configurable SIP connections and voice profiles. |
| Phone numbers | Local and toll-free numbers in 140+ countries. | Global number inventory; availability varies by market. |
| Pricing | Published destination rates; no per-trunk or per-channel fees. | Published destination rates; pay-as-you-go SIP with optional inbound channel plans. |
| CPS & capacity | CPS and concurrent channels adjusted on request. | CPS thresholds and applicable pricing depend on configuration. |
| Support | Engineering assistance with SIP configuration and routing. | SIP documentation, portal tools, and technical support. |
Your own PBX, SBC, or platform decides which calls go where. Keep Telnyx for what it already does well and route one defined workload to didlogic.
Your business applications keep a selected existing communications or platform workload on Telnyx, while a selected SIP voice workload runs on didlogic.
Your PBX, SBC, or voice platform sends selected traffic to didlogic and selected traffic to Telnyx, using routing rules you control.
You decide which workload goes where. Two providers do not by themselves mean separate failure domains or guaranteed redundancy; that depends on how each route is built.
Concrete properties of the network, pricing, and traffic you can verify before expanding a workload.

CPS and concurrent channels are raised on request, usually the same day, for the trunk that carries your test.
Outbound SIP trunking is limited to 20 CPS per source IP by default, with higher limits reviewed on request. A monthly surcharge applies above 5 CPS, based on the 95th percentile of hourly peaks.
Choose one market, route group, number set, customer workload, or outbound destination mix.
Confirm target destinations, caller ID requirements, SIP settings, and expected peak CPS before configuring the test trunk.
Use a customer-controlled PBX, SBC, or voice platform that supports the required routing.
Measure call completion, post-dial delay, caller-ID presentation, audio, DTMF or transfer behaviour, billing, unit cost, and support handling on comparable traffic.
Additional markets, traffic, or number moves remain optional later decisions.
CUSTOMER STORY
Family Dental Care needed a more familiar way to reach patients in Italy, Germany, and France. didlogic provided local phone numbers for all three markets, giving prospective patients a domestic number to recognize and call back.
CUSTOMER REVIEWS
Published reviews from teams running traffic through didlogic, on Trustpilot.
For a defined SIP/PSTN workload, they can be compared directly on the exact markets, routing requirements, capacity, operations, and economics. Telnyx also provides a much broader set of communications, AI, identity, networking, and compute products, so those requirements should stay separate from a SIP-only decision.
didlogic is worth evaluating when the application layer already exists and the decision is mainly about a defined telephony workload: SIP connectivity, numbers, routes, caller ID, or selected markets.
Telnyx may be the more natural fit when the wider Telnyx platform, for example programmable voice, messaging, AI, networking, or other native capabilities, is intentionally part of the architecture and consolidating those responsibilities is useful.
Yes, where the customer-controlled architecture supports separate workloads, route groups, markets, or multiple SIP connections. Keep ownership, routing, monitoring, and support boundaries explicit.
No. Two vendor names do not prove separate underlying carriers, routes, infrastructure, or failure domains. Redundancy claims should be based on the actual routing and architecture.
Use the same markets, call direction, minutes, average duration, number inventory, CPS, concurrency, and optional services actually used. For bursty outbound SIP workloads, include the applicable CPS model instead of comparing minute rates alone.
Usually, yes. Start with a separate outbound route group, a new number where appropriate, or another isolated SIP workload. Validate call behaviour, billing, operations, and support before making any production number move.
Yes. Telnyx offers programmable Voice API products and a broader portfolio that includes Voice AI, speech products, messaging, networking, and other primitives. If those products are central to the application, include them in the architecture decision rather than treating the project as SIP only.
