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 ?
