USG VoIP Issues

I have a new install with a USG, CK, USW-24, and some UAC-AP's. Ever since the install the Phones have not worked properly and CLI commands for firewall settings are not my specialty. Can anyone give me a hand? I need to get this working ASAP!!!!

Disable any SIP inspection feature: This option kills traffic between the phone and Broadworks, even though it was ostensibly included to help SIP work better

Ensure that VoIP SIP ALG option is turned OFF. It's ON by default and adversely affects call flows. Located under WAN settings

Re: USG VoIP Issues

Beyond disabling SIP ALG in the USG, are there any other VoIP "best practices" that should be done?

 

(Not to hijack the thread, but I have a client who is having VoIP issues with the USG.  They're ready to dump the VoIP provider, but I want to make sure there aren't other settings that should be configred to for VoIP.  I *think* it's the provider since everything was working well until yesterday.)
