Solved PBX Problem after V18 windows upgrade

[AWS2P]

Hi,
Tonight I did a windows V18.0.1.234 pbx upgrade and now everything has ended in V18 without any problem during reinstall, I get the PBX stuck with no more phones, no registred extensions, 2/3 trunks registred.
What i did, copied v18 exe in documents folder, copied last zip backup file from v16.8.9 , then from control panel , deleted v16, reboot after deletion, then install V18 with copied file from HDD, then ask for restore using my backup.
after the first failure upgrade, I did a second try with same complete reinstall ending with same problem.

So now I've no more V16 exe file to try to do a step back and restart customer PBX.

v16 installer: https://downloads-global.3cx.com/downloads/3CXPhoneSystem16.exe

Regarding v18: - are all services running in services.msc?

 

[AWS2P]

yes all green
Now I'm trying V16 with restore and see what happens

 

[AWS2P]

Well step back to v16 is worse, no more key activated, 265 updates and no more phones too , hope bmy backup is not corrupted

 

[AWS2P]

I'm retrying in V18 with new 3CX DL v18 exe file and another backup file, fingers crossed

Result seems exactly the same
services are up and running

I found my mistake , the SIP port isn't 5060 on this pbx , and during reinstall i missed during all my tries to switch 5060 to the port set

now residual problem is with GXP1625 phone missing like too often with GS phone

Hi @aws2p

The GPX1625 is slow to provision and react.

Please reset only one GXP1625, and reprovision it. Allow it up to 5 minutes to complete its task.

It should then register and appear under Phones section.

If it is ok, then you can do the rest of the GXP1625 too.

 

[AWS2P]

Please reset only one GXP1625

do you mean a factory reset or only a power off /on ?

 

[JohnS_3CX]

Do a restart and wait 5 minutes at least (it will automatically try to reprovision and maybe succeed).

Then if it fails to register, do a factory reset, then fresh provisioning, and wait 5 minutes to see the registration.

Please also check the IP Blacklist to make sure no phones were blocked.

Hi John,

Done , the GXP1625 came back alive after a power off only


you can close as solved
