Phone registered okay until we updated network (changed router). After this, phone failed to register, even after reboot, power off/on, factory reset. Could register phone by copying settings from failing Account 1 to Account 2 and then register (Account 1 still failed). Finally resolved problem by (i) saving configuration to file, and (ii) restore configuration from file. After this, phone would register okay.
We have about 9 phones, about half had this problem, was able to fix all of them with the file save/restore. Has anyone else seen this problem?

Hi,
We have not heard about this issue , could you please send me the trace that we can check?

Best Regards!

Quote: Unfortunately that did NOT work for us... Which means that our office is now without a phone system, unless we can reconfigure a couple of old Netcomm V85s to work temporarily.. This is such a Pain which we do not have time for.

We are using MyPBX phone system and three Yealink Voip handsets, one T26P and two T22P.
Like you, our office network were upgraded and hence a new subnet, ADSL router IP and DNS.
The MyPBX phone system seems to work ok, registering all FXOs and all external SIPs and two Netcomm Voip V85's worked without a problem, instantly registering, but all three Yealink refuses to Register, with a "Register Fail" on all three accounts. We have tried to reboot, save config and restore and also found the latest Firmware and upgraded all three handsets.
We are about to Save the config, reset to factory defaults and import config and see if that will make a difference...
Otherwise, these are great handsets and for the better part of the last two years, have been quite a reliable system.
The Debug Log says; "Device does not match ACL". What does that mean.
Would you have any other suggestions ?

Update...
We updated the firmware on the Yeastar MyPBX Std V4 to 2.17.0.37 Initially causing a total lockout.. Had to reboot MyPBX Again which would then allow us to Login again. Almost thought we would have to reset and start again.
Would seem to be a bit of a flawed update as MyPBX refused to display any settings on most of the pages.
Problematic because the documents stated that you cannot go back or down grade after this update.
Major Ouch...
The Line Status finally displayed the Extensions but as for the trunks, well, lets just say, we are still waiting. (After refreshing the page quite a few times, we finally got there) Trunks registered, Extensions are still NOT.

From online searches it looks like ACL is related to security, so it would seem that the phone systems may have locked the sip accounts somewhere. Not that we know where to look for this or how to correct it.
No change; MyPBX would still not allow the Yealink handsets to register, but still has no problems with the Netcomm handsets...
