Inbound Not Working UAE SIP Trunk

I configured the sip trunk in vicidial. Outbound calling is working perfect.
However i am not getting any inbound calls getting error:
from address missing 'sip:', using it anyway
empty domain name in FROM header
It's a landline sip trunk with one pilot number and 200 DIDs, DODs.
