Inbound calls ok but no outbound

Hello everyone
My inbound calls are ok, my outbound calls dont wotk, when i try call to any number i recive a message like “all circuits are busy now”…
I have tried so many times.
In my log have this:
[2025-09-04 12:57:19] WARNING[80665]: res_pjsip_outbound_authenticator_digest.c:577 digest_create_request_with_auth: 32682799:187.45.125.218: No auth objects matching realm/algorithm(s) ‘’ from challenge found.

How can i set realm?

Could you please share the full Asterisk call log details with us? Your post is too short..
( If needed, you may hide any IP addresses or personal information before sending. )

The current configuration you are using would also be useful.

Hi @MarceloJr
I agreed with @jcolp
Also good to see your test Endpoint some details. XXXX change to extension number.

> pjsip show aor XXXX
> pjsip show auth XXXX-auth

HI can you please first check that trunk is properly registered run asterisk -rx"pjsip show registrations" it could be due to wrong username/pass or authentication is set to none instead of outbound.

This doesn’t sound like a registration problem. In principle, registration should only affect inbound calls, but if the provider bends it to use as part of outbound authentication, I would expect it to send 401 then ignore and reject the offered authentication, rather than issue a badly formed challenge.
