If any of these are blocked the service may not work. Make sure these are all open through your ISP and any 3rd party routers with Firewalls.
5060-5061- Voice traffic for the Motorola MTA's 69 - DNS 53 - TFTP port (to register and get XML updates) 123 (Caller ID port Smile 10,000-20,000 - Main Voice traffic ports These are all UDP protocols.
Thanks for your reply. Here is what I have found: 1. Ports 5060-5061 seem ok because I ran the test at http://www.testyourvoip.com and it goes fine which tells me that at least port 5060 is open. (I did an Ethereal trace) 2. UDP port 69 is tftp which also is open because I get response when I run: tftp tftp.vonage.net get test 3. Port 53 works because I can resolve the addressess I type 4. Port 123 (time) is also open because I can sync my Windows clock with a ntp server About ports 10,000 - 20,000 I am not sure
It seems to me that there is a port that the router registers with Vonage (looks that might be a secret for some reason) that seems to be blocked. It would help me a lot if I knew what it is so I can tell my ISP to open it instead of shooting in the dark telling them to open various ports with no luck.
This is what I read from Vonage regarding ports 10,000-20,000 which suggests that if everything else was ok the adapter should login to Vonage anyway:
Quote:
RTP (Voice) Traffic: Ports 10000-20000 UDP. When a call is made, a random port between 10000 and 20000 is used for RTP (Voice) traffic. If any of these ports are blocked, you may experience one way or no audio
