Questions:
When using my Cisco SPA5xx IP phone and the other party hangs up, my phone waits a while then beeps several times before hanging up. Why is this? No other phones behave this way.
Can I make my Cisco phone disconnect as soon as the remote party hangs up?

Q: When using my Cisco SPA5xx IP phone and the other party hangs up, my phone waits a while then beeps several times before hanging up. Why is this? No other phones behave this way.
A: This is a feature on the Cisco SPA phones and ATAs and is designed to make our SPA phone more familiar to analog phone users.
For example, imagine the following scenario:
Bump your analog phone so that it is off hook. After a period of time, it will play a reorder tone to alert you that the phone is off hook.
You say, “oops” and replace the handset to silence the phone.
A Cisco SPA phone is no different, the remote end hangs up, but the SPA phone user does not hang up.
The phone is now accidentally off hook, so it plays a reorder tone, just like an analog phone would.
Q: Can I make my Cisco phone disconnect as soon as the remote party hangs up?
A: Yes. Modify the Reorder Delay parameter as follows:
Using the phone's web-user interface http://IP_address_of_phone/admin/advanced :
Regional tab > Control Timer Values (sec) > Reorder Delay: 255 [default is 5]
Or :
Using the phone configuration file:
<Reorder_Delay ua="na">255</Reorder_Delay>
Your Cisco SPA phone will now disconnect as soon as the remote party hangs up.
Here's how the Reorder Delay parameter works:
0 -- immediate reorder, play reorder for 10 seconds then on-hook
1 -- 1 second of dead air, play reorder for 10 seconds then on-hook
2 -- 2 seconds of dead air, play reorder for 10 seconds then on-hook
…
…
254 -- 254 seconds of dead air, play reorder for 10 seconds then on-hook
255 -- no reorder, immediate on-hook
