SMCD3G-CCR configuring to use with VOIP with Polycom VX410 Phones
I have been working with a customer who moved to a new office to setup everything for them. The voip phones are not working right they can call out however no one can call in. I have been on the phone with Polycom guys yesterday at that time Comcast had sent the wrong router it was the Netgear one so they have hooked up another last night the SMCD3G-CCR which is supposed to be good and work with these phone and voip. I have tried everything to get them to work and still cannot dial in. I have made sure the firewall setting were correct on the router where those two check boxes were checked. I also added port forwarding to port 5060 to the IP address of one of the phones then rebooted the phone and still nothing. Polycom tech says that he cannot see the phone on his end. Please help! Can anyone tell me what I need to do to get these guys phones working correctly. Thanks for any help that you can provide!
