Problems after new router

[wingsohot]

I personally don't recommend that setup as there will be problems with router firewall and port forwarding affecting the voice data packets.

It would be appropriate to change your connection to Cable Modem->N600 Router->HT502 ATA

Restart your devices (power recycle), it should be working fine then.

While I am not specifically certain about N600 model router, all new generation routers have inbuilt firewall and recognition and automatic port forwarding enabled for VoIP devices. HT502 is one of the device recognized by routers. I have 3 VoIP ATAs running in Cable Modem->Router->Switch->ATAs and I never experienced any loss of quality with any of the ATAs. Each network setup can be different, I am an experienced person in Network setup and my opinions are based upon my experience only. So yes, other's experience can be different than mine. I guess OP should contact support and they might be able to determine which setup is better for VOIPo service.

Thanks to everybody for their help... Unfortunately, I've several different suggestions and nothing has worked so far. What puzzles me the most is that going to from the cable modem directly to the WAN port of the HT502 with the router disconnected still doesn't work. I guess I'm going to have to contact customer support and see what they say because I'm out of ideas.
