OTE Registration no inbounds

SIP Provider in my country has changed some things. On my current installations i don’t have incoming calls anymore.
According to their instructions we have to change outbound proxy to sdvims.otenet.gr. I guess i put this in outbound proxy field in trunk settings.
Also they sent me something saying Remove OBP from Route. Change this to Yes. Is there a setting like this in VitalPBX?
