NO |
Problems even when in DMZ or bridged mode. Note that Comcast often brands this device and gives you no access to SIP ALG (some forums suggest Comcast SIP ALG can be disabled if you call them). Many problems reported with this device. Recommend replacing. Get a Motorola Surfboard modem (e.g. SB6141) and use your own router. Can then remove the Comcast rental fee for the modem. Will likely pay for itself within 6 months. I can personally attest to issues with CG3000 and spent way too many hours troubleshooting. |

Disable attack detection and put into pass-through mode to better router. Consider adding custom service to all SIP traffic through on ports 5060 through 5080. Many models give no access to SIP ALG so unable to disable. Some phones will have registration issues (e.g. Polycom) due to the inability to add DNS servers. Bridge mode is not effective so even doing this and using another router will not guarantee success. Also recommend editing UDP session timeout to something higher (e.g. 600 seconds). |
