Calls Failing with 487

I have created a new customer with new destinations and dialpeers and when i try to make a call the call fails. Below is the screenshot. on yeti switch it shows the calls has been disconnected from the termination but when i fetch the wireshark the call does not even go to the provider.

Unresolvable destination = termination gateway host can’t be resolved using DNS.

Thank you, There was a space added in the IP
