Cisco Access-List Ghost calls

I have created an access-list to prevent ghost calls but it doesn't seems to work. I only want receive SIP traffice from a specific IP address.

Access-List:

access-list 105 permit udp host 178.217.82.83 eq 5060 any log
access-list 105 permit tcp host 178.217.82.83 eq 5060 any log
access-list 105 deny   udp any range 5060 5080 any log
access-list 105 deny   tcp any range 5060 5080 any log
access-list 105 permit ip any any

interface Dialer1
 ip address negotiated
 ip access-group 105 in

Any ideas?

You're not restricting destination ports at your end coming in to your dialer interface.

Try...

access-list 105 permit udp host 178.217.82.83 eq 5060 any log
access-list 105 permit tcp host 178.217.82.83 eq 5060 any log
access-list 105 deny   udp any any range 5060 5080 log
access-list 105 deny   tcp any any range 5060 5080 log
access-list 105 permit ip any any
