- early offer disabled in sip profile (which is attached in sip trunk)

-  SIP Rel1XX Options , send Prack for all 1XX messages

- MTP enabled in SIP trunk

I'm a little bit lost, any help would be appreciated

On the logs I see State of The Call : STATE_DEAD and also SIP/2.0 503 Service Unavailable

You remove the IPs from the logs (which is fine for security, but next time just replace for something random like 5.5.5.5) so I'm not sure where is CUBE sending those messages but my guess is that it cannot communicate with the SIP provider IP.

Please check that.
