Hello,

I own SPA3000 and had the following problem,

1. VOIP(First Line) Echo problem
2. PSTN line Bad voice quality.

I did the fix this by doint the following steps(port forwarding). FYI, I copied it from other forum.

--> Pick up your ViaTalk phone and enter ****, at the Configuration Menu enter 110#. A voice will read you the IP of your adapter. Write this down.

--> If you are unfamiliar with how to enable port forwarding on your router, we recommend visiting the following site:
http://www.portforward.com/routers.htm

--> Your router's IP address will appear in the middle of the page. Highlight this address and paste it into your internet browser.

For example: http://192.168.15.1

--> Then, enter the setup for your router.
Default login: (blank)
Password: Admin

Routers may vary, but look for Port Triggering/Forwarding or something similar.


--> Type in ViaTalk(or your voip name) and the range would be 5060-5061. Set protocol to UDP. Put in the last digit of the adapter's IP address and then click enable.

--> For the second line, type in ViaTalk(or your voip/pstn name) and the range is 10000 20000. Set protocol to UDP. Put in the last digit of the adapter's IP address and then click enable.

--> type in ViaTalk(or your voip/pstn name) and the range is 10000 20000. Set protocol to UDP. Put in the last digit of the adapter's IP address and then click enable.

--> Apply/Save changes.

STUN would normally accomplish this automatically for you.

STUN is a much better solution for the 98% of us whose router is not the Symmetric NAT variety. In hundreds of ATA and softphone installations, I have never needed to manually forward ports through a router in order to make that ATA or softphone work. This is a good thing, because in many of these installations I did not have control of the router in question (hotel, airport, customer's office, coffee house, etc.).

Another thing I noticed is the non-standard (for Linksys/Sipura) RTP port range. Why would you need to forward ports 10000-20000 in support of ports 16384-16482? Isn't that overkill?
