When we pick up the receiver there is a beep beep sound. What do I need to do now? Does it have a message to retrieve?

I don't believe it's a malfunction. See if your current phone company has a voice mail active for your phone. If that's the case then odds are your voice mail is picking up before your answering machine.

You need to reset the phone to default settings.

The MMS delivery process is triggered by a special SMS message called the "MMS Notification". The "MMS Notification" contains a URL pointer back to the full content of the MMS message. So when the receiving phone gets the MMS Notification, it must connect to the URL in the notification in order to retrieve the actual message content.
The error that you include above looks like the URL cannot be fetched.
If it worked before, but it does not work now ... then it is possible that something has changed with regard to your firewall or network configuration. The receiving device needs to actually connect back to host server in order to retrieve the MMS content.
It is also possible that something has changed in the configuration at your mobile operator. Hope it will be helpful to you.

You should be able to go into message settings and turn the reminder beep off.You would find this under Message Settings, General, Message Alert.

each beep means a new voice mail...so 6 beeps should indicate that you have 6 new voice messages :D just dial your voice mail and check them and it will stop!!!!! :D
GOOD LUCK AND PLEASE RATE THIS POST!!!!!!!!

Remotely Operating Your Answering Machine

Call your telephone number and wait for the answering machine to answer. If the answering machine is off, it will answer after about 10 rings and series of beeping sounds.
During the greeting message (or a series of beeps when the answering machine is off), press [0] and enter your PIN code within 2 seconds (see "Setting a Security Code or Personal Identification Number (PIN)" on page 54).
The answering machine announces the current time and the number of messages stored in memory. You hear "To play incoming messages, press zero-two. For help, press one-zero." You will hear a beep.
Enter a remote command within 15 seconds, each command there after must be entered within 2 seconds.

I had the same problem.
Here is the solution that I received from Motorola tech support:

1.Delete all messages
2. Unplug the power and re-apply power
3. Quickly press and release << (previous message) and >> (next message) buttons together while the "Press review to receive setup instructions" message is playing.
The display will change from a segment scanning clockwise to anti-clockwise
4. Quickly press and release the On/Off button before the "Press review to receive setup instructions" ends. The display will change to a square scanning clockwise.
Note, this goes by quickly. I had to repeat steps 1-4 a couple of times before I got it right.
5. Press and release the delete button. The unit will emit a beep.
6. Press and release the on/off button. The unit will emit another beep and annouce "Press review to receive setup instructions"
Done!
