I´m having a problem that is probably trivial for you (not for me)
I´ve just installed an Asterisk@home 2.8 with 3 extensions (200 to 202) and connected via three FXO ports to extension lines coming from an old PBX.
These lines are the 142X form.
When an extenal call comes from the PBX via the FXO ports I can answer with no problem
Then, I want to transfer this call to a PBX extension, press “#” but then asterisk waits for an internal extension, so “1425” is a non-existent extension.
How can I signal that this is a PBX extension and not a AAH one ?
Thanks for your help.
