Hi,
I am new to CME, I have two offices (located less than 100 meters) both offices have CME 2900 series Version 15.2(4)M3 and more than 40 phone extensions.
I have one cable to connect between offices.
office 1 : phone extension starts 201
office 2: phone extension starts 301
employees on both offices should be able to call local extensions and other office extensions. Both offices are working separately now with below config.
Office #1
