How can I disable outside calls from fxo
to be transferred to outside.
does it, but disables transfer from inside also
Are there any solution?
How you extensions are numbered, how the external numbers, and do you use an access digit for outside calls ?
Outside calls starts with 9T and 2...
Please, can you expand? What is 2.. ?
Extensions are 3-digits, starts with (2)
To outside access (9) is pressed
Try transfer-pattern 9T
