My system is option 1C
There is a connection between my central (hotel 1) and another place central (hotel 2)
When I need to call a room in (hotel 2) I dial 77 then the extension number(xxxx).
Also when (hotel 2) need to call me, he dial 77 then my extension number (yyyy).
I heard that the IT engineer in (hotel 2) use this connection to use my trunk code and get the my external line.
How can he know my trunk code without I tell him (I mean can he inter central and print my feature codes ) and how he use the trunk code to get my external line.
Thank you
