Configuration for Grandstream HT812

[s2000]

Hi,

Does anyone know the proper configuration for a Grandstream HT812? Is it the same as a HT502?

Follow this guide: http://forum.fongo.com/download/file.php?id=2051. I know the ATA model is different, but the settings are similar.

Hi,
Do I still need to update the firmware per the user guide for HT701 or should I update to the latest firmware for HT812 instead?

I followed the setting without updating the firmware but I don't get a dialtone.

If you're having problems, then yes, updating device firmware is a good idea.

or should I update to the latest firmware for HT812 instead?

You’re always supposed to use your ATA model’s firmware.

That suggests your ATA isn’t registered, which shouldn’t have anything to do with firmware versions unless an older one was extremely buggy.

Check your registration status in the ATA by logging into it and navigating to status-->port status-->registration.

Also check registration status by logging in at https://www.freephoneline.ca/showSipSettings.

i) SIP Status needs to show "connected", and
ii) SIP User Agent needs to reflect a device that own and recognize. If you don't recognize the SIP User Agent, chances are you've been hacked.

Note that only one registration per FPL account is allowed at any time. When there are multiple devices/softphones using the same account, only the most recent registration is valid. The previous device will lose registration, and, consequently, incoming calls will not work on it. This is especially important to consider if someone else is using your SIP credentials (username and password) that are found after logging in at https://www.freephoneline.ca/showSipSettings or if you're trying to register your FPL account with a smartphone SIP app or with another device. Registration is required for incoming calls. It is not required for outgoing calls. A more significant concern, though, is that multiple registration attempts can lead to temporary IP bans. The more devices being used can make the temporary ban happen more quickly. Note that each time you reboot or restart your ATA or SIP app, it's attempting to register with Freephoneline again. Multiple registration attempts within a short period can result in temporary IP ban. Each time you reboot your ATA it's attempting to register with FPL's proxy server.


You should also check the light patterns on the front of your ATA. Refer to page 20: http://www.grandstream.com/sites/defaul ... _guide.pdf
