When I manually create a line to line transfer, I get "sorry your call did not go through" from the Telco.
The numbers I am dailing are valid and are not restricted in Toll/Ars.

My procedure is Ihave a live call, then press transfer, dial 9, then hang up.
I get a 20 second or more of dead silence, then 1 ring, then the above mentioned statement from the Telco.

Just for testing purposes, I tried to reproduce the Telco error message, and I did by dialing intercom 9 to go out on the T's, then I dialed 214-564-763 and left out the last digit on purpose, got the silence, and then the error message from Logix.
Could it be timing on the FX?
