Block WAN requests in ON, how to be removed?

[jpsegura]

Hi there

I have been on the IP blacklist for couple of weeks, I have waited and waited but still I am being blocked, is there a way to request to be removed?

Here is the last error message that I have while registering an anvil phone as router

SIP request (REGISTER) from 190.27.38.XXX was rejected. Reason: Block WAN requests is ON. Message: REGISTER sip:18XX.3cx.cloud:5060 SIP/2.0 Via: SIP/2.0/UDP

PLEASE HELP

Have you removed the IP phone from the extesnion? You can do this from another public IP other than the one that is balckisted, and then factory reset the IP phone that you tried to connect incorrectly.

Once this is done, please wait 24 hours, then ensure that the correct firmware is loaded to the phone before trying to connect it after installing a 3cx SBC on-site.

Thanks for the quick response.

While back I tried to install a phone that I though had router incorporated, and now I understand the amount of registration requests caused the ip blocking but that was a month ago, now I acquired a fanvil x4u phone with router, and firmware is updated and this is the one I am trying to install now.., somehow the ip remains blocked after my first failed attempt, but this was 20+ days ago..

I tried installing it in a different IP address but still have the same WAN blocked error.. will wait 24 h, and see if it goes away..

This is because the x4u is not router phone, you require the x4u- v2 for this.

Please see thus guide: https://www.3cx.com/sip-phones/fanvil-x3-x5/

Additionally check the firmware if you do decide to add it using an on site 3cx SBC.

Remove the phone from the user then factory reset it to them allow it to clear the blacklist after 24 hours.

Hi, this is me agan, got a fanvil V62 with router and still have the blocked wan message...
SIP request (REGISTER) from 190.27.XX.225 was rejected. Reason: Block WAN requests is ON. Message: REGISTER sip:18XX.3cx.cloud:5060 SIP/2.0 Via: SIP/2.0/UDP ,
Any option to remove the blocking?

Is it firmware 2.12.17? Phones may fail to connect properly if their firmware is too old.

Ok, it is now on 2.12.17.. but I guess I need to wait another 24 hours to tray again.. and finding another 24 hours wait for sure..

Thanks

I would also suggest that the factory reset the phone, log into the system from a different public IP, and remove the phone for the user's extesnion, as this will not be configured correctly. Then, after 24 hours, log back in re-provision as a route phone, following the guide carefully: https://www.3cx.com/sip-phones/fanvil-v-series/
