Twilio Elastic SIP Trunking connects existing PBXs and SIP systems to the phone network. Programmable Voice handles call logic through TwiML, Studio, and the Voice API.
Programmable Voice can use Twilio’s network or an external carrier through BYOC Trunking.
Compare didlogic and Twilio Elastic SIP Trunking using comparable routes and traffic.
Start with where your call logic runs. If your PBX, contact center, or AI platform already handles it, compare SIP connectivity, routing, CPS, and pricing.
See how to test didlogic with your existing PBX, AI voice platform, or Twilio setup.
Point a didlogic trunk at it and compare routes, CPS, and support against your current Twilio trunk.
Keep Vapi, Retell, LiveKit, or ElevenLabs; send one market through didlogic and compare the same calls.
Keep it on Twilio. Test any separate SIP traffic (a PBX, a dialer) on didlogic on its own.
| Decision area | didlogic | Twilio Elastic SIP Trunking |
|---|---|---|
| Network | didlogic-operated: own Autonomous System (AS13006), 12 physical PoPs, IP transit bought directly from Tier 1 carriers. | Twilio's cloud platform with regional edge locations. |
| Calls per second | Published rates by route and operator. | Published per-minute rates by destination. |
| Outbound rate structure | Published per route and operator, so you can check rates before you sign up. | Per-minute termination by country and zone. |
| Support | An engineer answers your ticket, 24/7. No separate support plan to buy. | Free plan: no guaranteed response time. Guaranteed response from $250 a month or 4% of monthly spend. |
CPS and concurrent-call capacity can be increased on request. Confirm the limits for your workload before testing.
1 CPS per trunk per region by default. Higher CPS is available through paid upgrades or account-level pooling.

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. An engineer helps you connect it.
Use one market, one route group, a test number, or a controlled share of outbound traffic.
Measure call completion, post-dial delay, caller-ID presentation, two-way audio, DTMF or transfer behaviour, billing increments, unit cost, and support handling on comparable traffic.
Increase route share, add numbers, or plan eligible ports only after the technical and commercial result is clear. Porting stays a separate decision.
If your PBX, SBC, or AI platform supports multiple SIP connections, it can send selected calls through didlogic while other traffic stays on Twilio.
Two providers do not automatically mean redundancy. That depends on how your routing is set up.
CUSTOMER STORY
A high-volume GoHighLevel customer needed didlogic routing while keeping its Twilio-based CRM. Our engineers delivered a native Twilio integration in five business days, enabling all three systems to work together without changing the CRM workflow.
CUSTOMER REVIEWS
Published reviews from teams running traffic through didlogic, on Trustpilot and G2.
Yes, when the part you want to change is SIP/PSTN connectivity. Compare didlogic against Twilio Elastic SIP Trunking on the same workload. If your product also relies on Twilio-native application logic, keep that dependency in place and evaluate the voice layer separately.
On didlogic, engineers answer support email 24/7, and urgent issues go straight to a network engineer, with no ticket queue and no scripts. Twilio’s free plan has no guaranteed response time; guaranteed response starts with its Production plan, priced at $250 a month or 4% of monthly spend, whichever is greater.
Twilio Elastic SIP Trunking starts at 1 CPS per trunk per region. Raising it (up to 5 per trunk, or pooled across the account) is a paid monthly add-on, and higher limits go through Twilio sales. On didlogic, CPS and concurrent channels are raised on request, usually the same day. Check both against your real peak.
Yes. Business accounts get a free test number after a short review. Ask sales about testing credit for outbound routes.
Yes. Elastic SIP Trunking is Twilio’s standalone SIP product. That is the relevant Twilio comparison for an existing PBX or SBC; Programmable Voice is a different application-level purchase.
Yes. Start with a test SIP connection, a new number where appropriate, or a limited route group. Validate call behaviour, billing, and support before deciding whether production traffic or numbers should move.
Usually, where your architecture supports multiple providers or separate workloads. Keep services outside the test scope unchanged and isolate the voice workload you want to compare. Validate any BYOC or other interconnection pattern before production use.
Use the same destination mix, call direction, minutes, average duration, number inventory, and capacity requirements. Include only the application-layer charges that actually remain in your stack. A single per-minute headline can be misleading when the architectures differ.
If an external platform already handles orchestration, speech, and agent behaviour, keep that platform fixed and compare the carrier layer separately. If your application logic is Twilio-native, keep that application dependency in place and isolate a voice workload only where a separate carrier test is useful.
Eligible numbers can be ported, but portability, documents, fees, and timing depend on the country and number type. Check the exact inventory before planning a cutover and keep the current service active until the port is confirmed.
