Livkeit SIP Service Testing: Outbound/Inbound Call Events & Statuses

[vlxdisluv]

Description
I'm looking for an easy way to connect to a room as a participant for testing purposes in livekit-sip service. The goal is to simulate and verify various SIP events (including error cases) during both outbound and inbound calls.

Background
When I deployed my code to the development stage, I encountered an unhandled scenario where the customer was busy. It would be nice to have a way to simulate this locally and handle it appropriately. The logs below illustrate the unhandled event:

Request

• Are there any recommendations, built-in tools, or best practices in the project for simulating SIP events during local testing?

Any advice or guidance on this topic would be highly appreciated.

Thank you!
