Prehistory: We have two IP-ATS in the office (historically it has been), two types of phones (Cisco and D-Link) are used, and the numbering on the ATS is also different.
History: A message arrives to the entire office: "Some employee in connection with the move to another room changed the phone number... bla bla bla...". It becomes interesting - because the phone number is not attached to the office. I write to admin:
The HHHH:
I don’t know how it is connected to moving and changing the number.
YYYYYY:
)) I dropped the phone dlink when carried on the tractor, and it stopped loading )
YYYYYY:
Others did not have to put the cisco.
The xxxx:
You won’t argue about moving. It is :)))
