Returned home from vacation. Had been lightening

What did the display window say after you plugged back in? With all plugged in and turned on, have you pressed the end-call key? If you still have an old non-electric phone, have you tried plugging that in, lifting and hanging up the handset? Have you tried ringing your carrier phone company to ask about the condition of your home landline, from another phone, eg a mobile? If you ring your home landline from another number, do you get 'busy' or does it ring, or what? Let me know how you go with these suggestions. Ta.
