@refined-appointment-81829 I'm unable to make an inbound call using Twilio. The livekit dashboard says 
invalid credentials were provided
. As per the documentation, it says Twilio Elastic SIP Trunking doesn't support username and password. Is there any other way around?
e
are you sure you are created an inbound trunk? is it via the UI or SDK?

I created it through the UI
r
Do you have a call id that failed? Do you have a PCAP?
a
yes

call id: SCL_nibZF28BXxDX

You've included 
authUsername
and pass for your trunk. That is why we are responding with the 407 challenge. Twilio should respond with a new INVITE that includes the proper HMAC.
Do you see any errors in your Twilio logs? Not sure why they do not respond.

i only got this
r
Also you have 
krispEnabled
If you are using this tunk with LiveKit agents it is more common to do krisp in the agent code rather than in the trunk code. Make sure you don't do it in both places. But this is not causing the issue you see above.
Is twilio setup to use a username/password? If not why have you defined it in your LiveKit trunk?
a
For the outbound trunk yes, but for the inbound trunk as per the documentation, it doesnot support. I was just trying it out.
r
I am not quite clear what you mean. You say inbound/outbound trunk but I am not sure if that is in reference to the LiveKit side or the Twilio side
a
Twilio doesnot support username/password auth for inbound calls. But supports for outbound calls.

Found the issue. I was using MangoApp for making the call. Seems like the app has some issues. I tried with my actual phone app, it's working now.
Thank you for your quick response
