Grandstream 502 kind of stinks

[usa2k]

How are they connected?
Asterisk => FXS => Grandstream 502 => Linksys DD-WRT Gateway/Router
Asterisk => Linksys DD-WRT Gateway/Router
Cisco ATA 186 =>

What kind of FXS, or is this a BYOD configure of Grandstream?

"My Linksys ATA and Cisco ATA 186 work great"
You have a 3rd ATA from Linksys too?

I guess I am confused.

This is a personal 502 connected to my personal Asterisk server. The 502 is plugged into a switch port on my Linksys WRT54G running DD-WRT, and so is my Asterisk box. My ATA-186 is also plugged into the WRT54G talking to the same Asterisk box.

I'm not sure what the 502 was trying to do, but it was transmitting something and causing problems. Unplugging it immediately fixed my speed issue! I don't know how far I want to go with troubleshooting, since my opinion of Grandstream probably should not be repeated

I had a lot of problems with the 502 disconnecting from the network, and I even captured trace logs and packets and put it in a ticket I opened with them. They told me switch out the power supply, and then started ignoring me. The ticket has been open since March and they simply stopped responding.

I have been running my 502 behind my router for well over a year now with no problem (current firmware .63).
