T20 and T21p registration problem - raltel - 12-29-2016 04:56 PM
I am starting to see this with specific extensions at specific install - Yealink phones (so far just T20 and T21p, latest firmwares) are coming un-registered from Asterisk even though the phone thinks it's still connected - under it's status it shows registered, but Asterisk says no.
I am having the problem with 16 phones, and not having it on the other 35 phones at same location.
The re-register time was reduced to 120 seconds.
All the system work in a dedicated vlan (using HP 1910 POE switchs), installed a year ago, and without configuration or hardware changes on recent time.
Thanks in advance.

Hi,
Did you reboot the specific phones who are un-registered to Asterisk and after you reduced the re-register time?
Are the phones now registered to Asterisk and how many time does it take till the issue occur again?

Hi,
If I reboot the phones, they register ok.
Note: I dont need to reboot, I enter the phone via web and clicking on "Confirm" in the Account tab (without changing any value !!!) I can see the registration in Asterisk CLI.
Reducing the re-register time (tested some values from 3600 to 60) dont solve the problem.
This issue occur with intervals of 2 or 3 days. Always phones of the same group of 16, and not simoultaneusly.
The only difference I find is that these phones have little daily use, but that happens from the first day.
PD: sorry for my english
