Grandstream adapter - strange behavior

[stevech]

not so here. Grandstream connects to Linksys WiFi router with switch. One port on that goes to a gigE switch.
In a call, only the one switch port on the Linsys flickers, and the WAN's LED.

Well, I don't know exactly what was happening but I do know that the problem was actually with the Netgear switch. For some reason it wouldn't negotiate a link with anything new, though existing connections still worked, which threw me off a bit. Rebooted the switch and now I'm able to negotiate a link with the Grandstream ATA. Also, after rebooting the switch the strange issue of all my ports blinking during a call also stopped.

Strange things were afoot. But all is well now, and no issues with the ATA.
