I don't know anything about that, but is this possible that the Fbus signal is 3vpp? If so you must have a level converter between your PIC and your Telephone, unless you may have weird results.
Still possible in think to supply the PIC @ 3V. Look the datasheet if it works @3v and 20MHz...
EDIT:maybe Fbus is open collector type too?

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
I try using a converter like that max232 and ds275 but the same problem I can transimit but i can't recieve , I will try to use 3V power if its will working or not ?
try a simple pull up on your PORTC.5 pin.
If you use a MAX or else inverter, you may need to change your baudrate settings to INVERTED mode (16468).
Did you tried with a PC and a MAX232?
