T58 Handset dead / after update no service

[dmaack]

Hello

i use a tw 58 phone and the handset stopped working.
after contacting yelling support i upgraded the firmware and now the BT handset works again.
unfortunately the phone tells me now "no service".
i did not make any changes.

after looking up the call list i discovered the following:

all working calls were like this

155@192.168.2.1

155= numbr of the phone

192.168.2.1 = IP of phone router



now when i try to call someone it says

ip phone@127.0.0.1 which is localhost?



also after update it automatically changed the screen pin lock to 123 for some reason

can someone point me in the right direction to fix this.

appreciate your help and tips

kind regards
