3. Pressing 1 sends a webhook doors to n8n.
4. Pressing 2 sends a webhook loft to n8n.

7. n8n creates an application ID.
8. The Telegram link opens the correct script.
9. Before the script, the client confirms consent.

Hello! The task is clear — I will set up the complete connection: Asterisk + Kyivstar SIP, IVR, n8n, Telegram bot for reading products from OpenCart, SMS for those without Telegram. Security, auto-start, instructions — everything is included.
Two clarifications:
Does Kyivstar provide a static IP for the SIP trunk or a dynamic one? This affects the connection scheme.
Which service do you plan to use to send SMS — is there already a gateway or do we need to find one?

I will install Asterisk with PJSIP on Ubuntu Hetzner and connect the Kyivstar trunk via IP authorization. IVR, through extensions.conf with separate contexts for doors/loft/complaint/missed_call, each sends a POST to the n8n webhook; n8n generates a request ID and sends a deeplink to the Telegram bot, which reads products directly from the MySQL database ocStore. Fail2Ban + iptables whitelist only for Kyivstar IPs, AMI is closed on localhost. Question: is there a ready list of Kyivstar IP ranges for the whitelist, or should I clarify with the provider during the setup process?

Hello! I am ready to implement your custom ecosystem without third-party CRMs. I have extensive experience with Hetzner architecture (Ubuntu + aaPanel), VoIP telephony, and automation systems.
How I will solve your task:
Asterisk (PJSIP) + Kyivstar: I will configure the SIP trunk with IP authorization, routing, and IVR. Each key press will generate the corresponding Webhook in n8n.
Maximum security (Priority): I will set up a strict firewall (allowing only Kyivstar IPs), Fail2Ban, close AMI/SIP from scanners, and completely block guest, international, and unauthorized calls.
n8n + Telegram: I will deploy a local n8n, build scenario branches, generate request IDs, verify client consent, and send SMS fallback.
…
Integration with OpenCart: I will configure secure requests from the Telegram bot directly to the ocStore database for dynamic product card output (price, photo, link).
I guarantee the completion of all 20 points on your checklist, uninterrupted operation of the site on aaPanel, correct auto-start of daemons (Asterisk/n8n) after reboot, and I will provide clear documentation/instructions.
I am ready to discuss the details and start configuring the server!

We are Devoxen, an IT outsourcing company specializing in backend solutions, automation, and integrations. We have practical experience in setting up IP telephony based on Asterisk, including working with SIP providers.
Connecting Kyivstar via SIP is well known to us - we understand the typical nuances (registration, NAT, codecs, call routing) and immediately incorporate this into a stable configuration.
What we will do:
- set up a SIP trunk with Kyivstar
- check registration and connection stability
- configure inbound/outbound routes
- implement IVR, queues, and call forwarding if needed
… - test and bring the system to stable operation
We work in stages: first, we ensure stable connectivity, then the logic and optimization for your tasks. After launch, we remain in touch for support and adjustments.
We are ready to start soon.

For sending to the client:
Hello! My name is Matviy. I have extensive experience in setting up complex automation systems that combine telephony, bots, and databases. The project is clear to me — it involves creating a fully autonomous CRM based on Asterisk and n8n without third-party services.
I have experience integrating complex solutions: linking Python/n8n with website databases, working with Webhooks and Telegram bots of any complexity. I clearly understand the security requirements (PJSIP, Fail2Ban, ACL for Kyivstar IPs, and closing AMI/ARI), as I often work with financial bots where server protection is priority number one.
How I will implement your task:
Asterisk: I will install and configure a PJSIP trunk from Kyivstar with strict IP filtering. I will set up a dial plan with IVR and sending Webhook to n8n.
…
n8n + Telegram: I will deploy n8n on your server, create scenarios for processing incoming/missed calls. The bot will be directly connected to the OpenCart database via SQL queries to retrieve current products and prices.
Security: In addition to Fail2Ban, I will configure the closure of all unnecessary ports through UFW and disable anonymous calls.
Please let me know if you already have access to the OpenCart database (host/user), and if SMS configuration is needed through a specific gateway (for example, TurboSMS or AlphaSMS)?
