Hi,
Yeastar S20 (last firmware) with one card ISDN BRI on board.
Trunk BRI1 (Network)
Trunk SIP Register trunk
Inbound Routes: ISDN to SIP, SIP to ISDN (Destination: Outbound Route)
Outbound Routes: ToSIP, toISDN
I Have a ISDN PBX connected on Bri1 (Or a simply ISDN Phone)
When External user call Sip number, the ISDN Phone Ring and work
When the ISDN Phone call out , i hear Busy tone immediately.
How can i resolve ?
Thanks so much
Simone Zerbin
Try get some logs and post here for further analyse

Ciao Simone ,
can you post the Dial Pattern in the OUTBOUND Route and the BRI TRUNK setup ?
Do you use TIM (Telecom) , Fastweb, Wind , Vodafone ?
Try to add XXXXX. to dial Pattern and see what happens.
RESOLVED!!!!
In the Trunk connected at the ISDN PBX:
Trunk / Advanced / Overlap Dial
Set to Inbound (default Disable)
Elvis: the outbound Trunk is: TIM Voip (Sip Registered)
