SIP call fails with fast busy

[dwentworth]

I have received complaints that certain phone numbers give you a fast busy when you dial them.  Most calls have no issue.  I have attached the call output from the SIP Cube of a calls that complete & a couple that doesn't.  Any advice would be appreciated.  My environment consists of:

call manager v11.5

pub in DC = 10.56.1.10

sub is local in corp office = 10.18.84.30

Can you share "debug ccsip messages" for one failed call along with calling and called number to check further

Thank you for your reply Rajan but this was just resolved with a restart of the UCCX server. Not sure what the UCCX server has to do with this as I'm not a voice guru but I'm going to check for any correlation.
