5. As an old retired phone guy

The buzz is an indication of trouble on the line. It could be in your wiring or in the telco's cable. The cordless phone is electronic and is probably more sensitive to the line issue, not allowing you to call out. It might work if you switch it from touch tone to dial pulse.

The buzz may be causing the tone receiver in the central office from recognizing them. Dial pulse is basically a make or break of the DC. It is always available on landlines.
