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 .

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.
