Is it possible to disable SIP ALG on the Cisco DPC3848? About once a week something gets out of sync between the Cisco router and my VoIP ATA, and it starts dropping calls. Rebooting the Cisco fixes it. The VoIP provider says that it's due to the known defective SIP ALG implementation in Cisco routers, which should always be turned off if possible. Unfortunately the DPC3848 doesn't seem to expose the SIP ALG setting, unlike many other routers.
