VoIP Problem - Sipura SPA-2100 and D-Link DIR-628 WiFi router

[metroplex]

I have been using a Sipura SPA-2100 VoIP modem for over 3 years without any issue. I have a cable modem connected to a Linksys BEFSR41, with the SPA connected to the Linksys.

I recently acquired a D-Link DIR-628 WiFi router (Rangebooster N) and implemented network segregation:

Cable Modem -> D-Link -> Linksys

I had connected the SPA to the Linksys and it failed to connect to its servers. I then switched it to the D-Link without any success. I fail to see how it can't connect since all of my other PC's function normally. The transition was 99% smooth. The 1% was the problem I am experiencing with the SPA.

Any ideas?

if the sipura wont work with either the linksys (where it had been working fine) or the new dlink then i would think that its probably the sipura thats the problem, or your service provider you use the voip box with.

or maybe the cable has gone bad from the sipura to the router, have you tried another cable, or can you ping the sipura when its plugged in?

The D-Link detects the Sipura but the Sipura just wouldn't connect to the VoIP server. After more fiddling, it seems the Sipura works with the D-Link but not the Linksys in the segregated network.
