Davi,

Have a read at link
http://www.cisco.com/c/en/us/td/docs/ios/12_2/voice/configuration/guide/fvvfax_c/vvfclid.html#wp1077886

You need to know when to look for and apply the CLID
In the UK we use " caller-id alerting dsp-pre-alloc"

Try a couple of different option and see if it helps

Hope this helps
