N8n with phone numbers issued from didlogic.com

Questions

Hi everyone,

I am based in Dubai, UAE and need an AI calls automation setup here using UAE-issued dialer phone number. I’m currently exploring ways to handle outbound voice calls via n8n, and I’d appreciate some guidance.

Our current setup uses Twilio, but since their UAE toll-free numbers don’t support outgoing calls, we’re considering switching to DIDLogic.com — which offers SIP trunking and international voice termination.

I’d like to understand:

  1. Has anyone successfully integrated DIDLogic (or similar SIP-based provider) with n8n for outbound calls?

  2. Does DIDLogic expose an API endpoint (or webhook) that n8n can trigger to originate calls, play audio, or track call status?

  3. What would be the best approach — should we connect through HTTP Request nodes using their API, or use a custom SIP client / VoIP server layer in between (like Asterisk, FreePBX, or Kamailio)?

  4. Any tips on how to receive callbacks/webhooks in n8n for call status updates or recordings would also be helpful.

Basically, I want to create a workflow like this:
→ n8n trigger (e.g., webhook or CRM event)
→ initiate an outbound call via DIDLogic
→ update call results/status back to CRM (e.g., GoHighLevel)

If anyone has experience doing something similar (even with another SIP provider), I’d love to hear your implementation or best practices.

Thanks in advance!

hey Wasim,

so ive not personally integrated didlogic specifically, but ive done similar stuff with twilio and other voip providers, so i can point you in the right direction.

**real talk on didlogic:**

first thing - check if didlogic actually has a REST API. a lot of SIP providers (especially regional ones) dont expose much beyond SIP trunking. if they only do SIP, youll need a middle layer. but their docs should say what they support.

**your options depending on what didlogic offers:**

**option 1: if they have an API**

- use an HTTP Request node to call their API endpoint for originating calls

- most voip APIs work like: POST to `/calls` with `{to, from, audio_url}` or similar

- then set up a Webhook node to receive their callbacks for call status (connected, ended, failed, etc)

- parse the webhook payload and do whatever you need (log it, store in db, trigger next step)

**option 2: if theyre SIP-only**

this is trickier. youll need something between n8n and didlogic that speaks SIP:

- **Asterisk/FreePBX** - overkill for most cases but it works. you run it locally or in a container, n8n makes HTTP calls to asterisk’s API (ami or ari), asterisk handles the SIP stuff

- **Kazoo/2600hz** - another pbx option but again, adds complexity

- **simpler: check if any n8n-compatible service wraps didlogic** - like maybe a voip-as-api provider that uses didlogic as their backend?

**what i’d do first:**

1. grab didlogics documentation and see: “do we have REST API docs?” - thats your answer

2. if yes to API - grab a sample API call from their docs, drop it in an HTTP Request node and test it

3. if no API - youll likely need asterisk or similar (bigger lift)

**for webhooks/callbacks:**

n8n handles this easy:

- create a Webhook node (trigger type)

- theyll give you a URL like `https://your-n8n-instance.com/webhook/xyz\`

- add that to didlogics callback settings

- when they call it, your workflow triggers and you can parse the status

**quick checklist:**

- confirm didlogic has API (not just SIP)

- get their API docs

- test a sample call in HTTP Request node

- set up webhook for callbacks

- handle call status in your workflow

lmk what didlogics docs say about their API - that’ll tell us if we can keep it simple or if you need asterisk running
