How do I disable SIP-ALG in my router or firewall?

My company is moving to VOIP phones and we were asked to disable SIP-ALG. I ran the command and performed the test that the company wanted me to run. In the test results it's still showing the SIP-ALG is enabled. Has anyone ran into this issue? Below is the command I used .

config t
policy-map global_policy
class inspection_default
no inspect sip
end

no ip nat service sip tcp port 5060
no ip nat service sip udp port 5060

That's how to disable ALG on Cisco routers.

Can you describe what would be possible impact if we execute these commands in our router in production?? Thank you.
