I have been having problems trying to setup a VOIP system under the following conditions:
- My ISP is Southbell, I am suscribed to their DSL which uses PPPoE
- My Router is Linksys WRT54GS
- My ATA is a brand new SPA-2002
For three days now I have been working with my VOIP provider technicians trying to get the system to work. They have supplied all the information that is normally required to connect to their server but they have finally admitted that they are not familiar with the SPA-2002, Up to date, we have been unable to register the ATA with their server. The end result is I have reached a dead end.
Here's what Sipura has to say (quote):
"...The adapter does not have a pppoe option for connection, therefore the adapter does not connect to the internet. You can use the router to ensure that the adapter connects to the internet. But you need to open the ports mentioned in my previous e-mail. Use this for reference: "
"If you have a firewall, make sure you are not blocking the UDP PORT5060,5061 and port for UDP packets in the range of 16384-16482. You will also need to disable "SPI" if there is such function in your firewall. Depending on the SIP server that you are going to register to, If it supports NAT, then you can use "Outbound Proxy" configuration of the SPA to connect to it. Otherwise, SPA also supports STUN protocol. (see "SIP" tab config from web GUI) Please note that STUN will not work if you have a symmetric NAT. If you enable the debug through syslog, and set "STUN test" to yes, SPA will print information about whether or not you have a symmetric NAT."
Being an absulute novice in this field, it is hard for me to implement Sipura's recommendation specially since (to me) they are kind of vague and do not refer specifically to the Router that I'm using.
Is there someone that can give me some advise and/or guidance on this matter considering the setup that I have? I would most certainly appreciate it. Thanks and best regards,
