Hello & Welcome to Just Answer,
I'm Greg and will do my best to assist with this issue today.
Sorry I didn't see your question earlier and to hear of any issue with your phone(s).
if you still need help with this issue, may I ask:
1) How many TOTAL cordless handsets do you have with this system, and if more than one, do ALL handsets have this issue?
2) When mentioning "call is disconnected after a few minutes", is there ANYTHING on the display of the handset - after the disconnect?
3) What landline phone service provider (phone company) you have for this phone line?
Please REPLY using the box below and the SEND button.
