Cisco DPC3939B & "SIP VIG"

We just got our Comcast line install, it come with DCP3939B router.

In search, I found following and it stated "SIP AIG is enabled by defaulted and cannot be disabled"

https://kb.intermedia.net/article/3138

 

We have Toshiba VoIP phone and without disable "SIP AIG' it will create "Disconnected" and "Audio issue - other party can hear but we can not hear"

 

Anyone have experience on this area?

Hi long and welcome to the business forums.

 

Thanks for your question on the gateway. The SIP ALG is disabled by default and we are unable to enable it. 

 

Please do let me know if you need anything.
