Global SIP trunking on direct carrier routes
What you get with didlogic SIP trunking
Voice that stays on our network from start to finish
didlogic runs its own Autonomous System, AS13006, with owned hardware in 12 carrier-dense data centers across APAC, Europe, Oceania, Africa, and South America. We buy IP transit directly from Tier 1 carriers and peer at major Internet Exchanges. Local traffic stays local. Regional traffic stays regional.
That is how we hold sub-20ms audio latency on 80% of calls. The remaining 20% are long-haul or cross-region paths where physics and carrier geography take over.

CLI Rotation for outbound performance
CLI Rotation lets you manage a pool of caller IDs directly from your didlogic account. Outbound calls cycle through the pool automatically, which spreads traffic across multiple numbers, keeps each one under spam-detection thresholds, and pushes answer rates back up.
The feature is self-service. Add numbers, remove numbers, and update the rotation logic from the portal. Changes apply instantly, with no ticket and no engineering involvement on our side.
Reliable, compliant voice infrastructure with real engineering support
• Regional data processing
Voice traffic runs through our own regional data centers. Call handling stays on domestic infrastructure where local data laws require it.
• Licensed local voice in 17 countries
In regulated markets, we provision DIDs on local licenses. Outbound calls originate from in-country IPs with compliant caller IDs, so they arrive as domestic traffic rather than being blocked as foreign.
• Encrypted signalling and media
TLS for signalling, SRTP for media across inbound DIDs and outbound trunks.
• E911 and E112 in 46 countries
Emergency routing where required, with address provisioning built into the portal.
• Real engineering support, during migration and after
Reach our engineering team directly during migration, integration, and escalations. We also respond in platform communities like Vapi Discord when customers need help in public.
Our team has been running voice infrastructure for 20 years, and regional engineers track regulatory and carrier changes in every market we serve.

FAQ: SIP Trunking
What makes didlogic SIP trunking different from a typical SIP provider?
didlogic SIP trunking is built on direct carrier routes rather than a pure reseller model. The page positions didlogic around owned infrastructure, including AS13006, 12 physical PoPs, direct Tier 1 peering, local traffic staying local where possible, and a pricing model with no per-channel or per-trunk fees.
Is didlogic a good fit for AI voice agents?
Yes. didlogic is a strong fit for AI voice teams that need local numbers, low-latency routing, HD audio, and SIP handoff to human agents. If your main use case is conversational AI, outbound AI calling, or voice bots connected to real phone networks, the AI Voice page gives a fuller picture of how the platform supports that workflow.
Can I use didlogic SIP trunking with local DID numbers?
Yes. SIP trunking and DID coverage work together, so businesses can connect voice infrastructure and provision local numbers through one provider. If you want to explore number availability and country coverage in more detail, see Local DID Numbers.
Does didlogic charge per channel or per SIP trunk?
No. didlogic does not charge per channel or per trunk, which makes the pricing model easier to work with for businesses that need flexible capacity or expect traffic volumes to change over time.
How quickly can I start testing didlogic SIP trunking?
In many cases, you can create an account, get a test DID, add credit, and start placing calls the same day. That makes it easy to validate routing quality, setup compatibility, and call performance before scaling further.
Which PBXs, softphones, and platforms are compatible with didlogic SIP trunking?
didlogic SIP trunking is designed to work with common PBXs, softphones, contact center systems, and AI voice platforms. It is suitable for businesses that want to connect existing voice systems without rebuilding their telecom stack from scratch.
Is didlogic suitable for outbound dialers and telemarketing?
Yes. didlogic supports outbound use cases where answer rates, caller ID management, and route reliability matter. Features like CLI rotation and destination-specific routing make it relevant for dialer-heavy teams that need more than a basic SIP provider.
How does didlogic handle voice quality and latency?
didlogic positions voice quality around short routing paths, direct peering, and infrastructure control. That approach is especially important for contact centers, sales teams, and AI voice applications where latency and audio quality directly affect call performance.
Is didlogic a Twilio alternative for SIP trunking and AI voice?
For teams focused mainly on voice infrastructure, it can be. didlogic is better positioned for buyers who want SIP trunking, DID numbers, and direct telecom connectivity without paying for a broader communications layer they may not need. If you want a more direct side-by-side view, the Twilio alternative for AI voice
Does didlogic support compliance and security requirements?
Yes. didlogic is positioned for businesses that need regional routing control, secure signalling, and support for regulated markets. This is especially relevant for financial services, international operations, and businesses that cannot rely on generic voice routing.
Can didlogic help with migration and onboarding?
Yes. didlogic supports onboarding, migration, and engineering-led setup help, which is useful for businesses moving from another carrier or adding a second voice provider for testing and redundancy. If you want to speak with the team directly, use the contact page.
Who should contact didlogic about SIP trunking?
didlogic SIP trunking is relevant for AI voice teams, contact centers, outbound sales operations, telecom platforms, and businesses expanding voice coverage across multiple countries. If your setup is more complex than a standard self-serve flow, it makes sense to contact the team and discuss the use case directly.
