Yeastar MyPBX and Elastix IAX trunk

Good night

I have the following problem.
The IAX trunk connects without any problem between the two systems.
But whenever I try to connect to Yeastar extensions from elastix (or otherwise), get information "all circuits are busy now."
I want to connect the two systems, through an iax trunk with username and password.

Without using any authentication works perfectly.
Someone can help me?!?!? Thanks

My configuration:

Elastix Server:

Outgoing Settings:

Trunk Name: Test

PEER Details?:
username=username
type=user
trunk=yes
secret=password
qualify=yes
host=Yeastar_IP
disallow=all
context=from-internal
allow=alaw

Incoming Settings

USER Context?: test1

USER Details?:
secret=password
type=user
host=Yeastar_IP
disallow=all
context=from-internal
allow=alaw

Register String?: {Blank}

YEASTAR:
Type: IAX
OperatorName: Test
Hostname\IP: ElastixServer_IP
UserName: username
Password: password

Please don’t duplicate threads. You need to show us the cli output of the call, iax show peers and the iax2 debug.

Or maybe Yeastar has some advice? They sold you something, right?

I have yeastar PBX connected to Elastix and working well !

check your inbound route configuration.
