I'm still trying to properly setup my UC320W with a bunch of SPA504 phones. I believe I have almost everything working ofr the most part except for the fact when I call in, I get no sound on any of the phones. I am able to call out on these phones though but just get no sound on incoming calls. I'm sure I did have this working at one time but I can't figure out why/how this has changed. Any help would be appreciated. Thanks.
I have attached a TCP dump. The IP address for the config utility is 192.168.1.200 and the other IP address which I believe is the WAN address is 192.168.1.103. Strangely enough, when using the TCP dump tool, the audio worked in incoming calls but when it is turned off, it doesn't work.
The tcpdump somehow doesn't include a successful call. There are a couple of INVITE messages with authentication failure. You may want to contact small business support center to get help. So that the engineer can look into your configuration and get a successful TCP dump.
