If that is the system I think it is (IRLP) you need to know the rules of the repeater you are using.. Some require all commands to be PREFIXED, Some do not.
If it does you send prefix-1234 on your DTMF (Touch Tone (tm)) keypad and release, you should hear 'Connected to node 1234" and some other stuff.
Sending 73, terminates the connection.
If it's prefixed you need to talk to the repeater's operator (owner) to find out the proper prefix.,
