Hi all. I have received a SIP IP-to-IP trunk from the provider without authentication. I configured it according to the scheme AvayaCM=>AvayaSM=>AvayaSBCe=>Provider side. Outgoing calls work, but the problem is with incoming calls. When dialling a number the call gets stuck at Avaya SM with the error "SIP/2.0 407 Proxy Authentication Required". But there is no authentication on Avaya SM. Please help me understand what could be causing this.
172.25.0.7 Avaya SM
172.25.0.62 Avaya SBC
172.25.0.9 CM
