Disabling the SIP ALG in a VoIP profile

Disabling the SIP ALG in a VoIP profile

SIP is enabled by default in a VoIP profile. If you are just using the VoIP profile for SCCP you can use the following command to disable SIP in the VoIP profile.

config voip profile

edit VoIP_Pro_2

config sip

set status disable
