ATA not connecting after replacing router

Post by khan »

Hi
Can anbody help me here as I just have replaced my router and the new router is Linksys E1200. My computer and laptop is connecting to the internet and working fine but my Freephoneline ATA (Grandstream HandyTone-286) is not connecting and red light is blinking all the times. It was working fine with my old router but with my new router it is not connecting with internet/sever. I will appreciate if anybody can advice me what to do as I believe there must be something wrong with my router. Thanks for your suggestions and help in advance.

There could be a few things that might cause this, but doing a factory reset on the ATA and setting it up again might be a blanket solution that would weed out many of the problems.
If your ATA had a static IP for example, it might not be on the same IP range as your new router.

You also might find that powering down your ATA for 10-20 minutes and then powering it back up again might help fix thing. It seems that some ATAs can get stuck in a bad registration and this usually fixes it.

The new router is a heap of junk that uses a brain dead implementation of SIP ALG! I do not know if you can disable it on the router, but I have some ideas. the best option is the first option.

Option 1: Flash this router to a 3rd party firmware like DD-WRT. When you do that, you will now have a stable router, that is not a buggy hunk of junk as your current router firmware.

Option 2: Switch the SIP port on the ATA from port 5060 to 6060 to bypass SIP ALG. You still have to deal with buggy, and historically insecure firmware.

Option 3: Disable SIP ALG, if possible. You still have to deal with buggy, and historically insecure firmware.

Option 4: update your firmware to the latest and greatest, and hope Linksys fixes the issues that should have already been fixed the first place. The company has been at it for 20+ years, you would think they would have gotten a handle on the firmware right by now!

You should forward SIP and RTP ports from the router to the ATA, so the router does not have to "guess" where to forward SIP packets.
