Anyone from New Zealand using RetellAI? I am trying to use One.NZ SIP trunk settings and it just does not work. I can make the SIP trunk work from my laptop using a soft phone. Thanks, Imran. ---

I think the issue is because you’re connecting your SIP directly to Retell. In my case, I’m using a slightly different approach I don’t connect directly. I use a control layer in between to handle the SIP session and routing first, then pass it to Retell. That setup makes it more flexible (especially for providers that require registration) and gives better control over the call flow like transfers, callbacks, etc. I treat Retell as part of the system, not the main endpoint. I’ve been sharing my build progress and architecture on LinkedIn if you’re interested to see how it’s structured [https://www.linkedin.com/in/andri-febri-nugroho](https://www.linkedin.com/in/andri-febri-nugroho) ---

The issue here is that your provider requires that you “Actively Register” with their system, in order to make/receive calls. Retell doesn’t support that workflow. I may be able to assist you via Cloudonix. Please contact me via Discord or a DM for more information.
