SIP INVITE Fails with 403 Forbidden on LiveKit

[narendra-bluebash]

We're encountering an issue while setting up outbound SIP in LiveKit. The response to our INVITE request returns an unexpected status: SIP Status: 403 (FORBIDDEN).

Here are the connection details we're using:

SIP Address: a2east.sipregistration.com

Username: XXXXX

Password: XXXXXXX

Number: XXXXXX

We’ve verified these credentials using Zoiper, and both inbound and outbound calls work successfully there. Could you please help us debug this issue?

same problem, with 2 sip providers:

• Mango (RU)
• Belline (RU)

heeelp, please. How can i debug this case? all logging: debug is set, but no details in docker consoles, in sip container too. Just 403 Forbidden error

Answered in Slack. We'll need PCAP to debug this.
