Solved Yealink T42S will not provision after factory reset

[ihall]

The phone is showing as "new" in my phone list. I assigned it an extension and it will not provision. I have factory reset this phone a few times and tried to use the auto provision link through the phones web interface, but it will not grab the phone. not sure what else to try. This phone was assigned to an extension, on the system but when I went to update the user settings in 3cx it forced me to update the password for authentication (said it was too short). After this it lost communication with the phone. I figured factory reset and reassign was the simplest thing to fix it, but guess I am wrong.

3cx version = 18.9 build 20

Yealink phone
model = SIP-T42S
FW = 66.86.0.5

Any thoughts on next steps?

Looking at this again, now the phone is not showing in "new" in the phone list, but still will not provision. I am not sure what else to try at this point.

Have you checked the IP blacklist?

Since it did show up and after some fiddling it does not its worth the check.

that was it. it ended up on the blacklist. Thank you for taking the time to respond. I never even thought about looking a the blacklist in this situation.

Glad to be of help , did it state why it was blacklisted? the reason can point into the direction of the solution to your issue.

i think it said something about too many invalid passwords. I was able to provision the phone after removal from the blacklist. I assume when I updated the password to 10 characters it somehow did not sync that to the phone, so it was using the old password to register and ended up being black listed. The factory reset did not work because the IP had been blacklisted and the timing was just "bad". So I went through a lot more steps then needed. thanks again.
