I have VOIP phone service with Jivetel using a Linksys spa2102 VOIP device. I recently purchased a new Edimax BR-6428ns wireless n router and plugged my linksys device in through it. I made the following config changes to my router:
- Set the Linksys VOIP device with a static IP
- Turned on the Firewall and set the DMZ to be the linksys device
- Disabled SIP under ALG (I was told to try this by Jivetel), also tried with it enabled
When I pick up my phone (a Siemens A16), I hear a beeping dial tone followed by a busy signal and I cannot dial out. If I plug my other phone (a Panasonic KX-TG4321B), I still here the same tones, but I can dial out before the busy signal and it works.
Jivetel told me there must be a setting somewhere in the Edimax causing the problem and they cannot help me anymore! What can I do to fix this problem?
