My F480 doesn't ring when called

Hello, Mary -

I checked the user manual for your Alcatel 3003G cell phone:
https://www.manualslib.com/manual/1150047/Alcatel-Tribe-3003g.html?page=1#manual

I did not find any information regarding increasing the length of time of rings of incoming calls in the manual. So, I thought the incoming rings length of time may be dependent upon your cell phone service provider, Vodafone.

I found some information on a Vodafone Support page:

How to increase the time before a call goes to voicemail?
(Quote)
Your Vodafone mobile is set to ring for 15 seconds before going to voicemail. You can change how long it rings for, choosing from 5 to 30 seconds in 5-second intervals.

To choose your desired ringing time:

• Enter **61*121*11* on your Vodafone mobile
• Choose the number of seconds you'd like your phone to ring for, followed by #
• Press Call
• A confirmation message will pop up on your screen with your new ring time

For example, if you want to set your Vodafone mobile to ring for 25 seconds, you enter **61*121*11*25#, and press Call. When the message pops up, you'll know it's all done.

Watch this simple video to find out how to increase the time before a call goes to voicemail.

Best wishes.

you did not provided what brand, model and year, therefore you need to read your manual...

you need to find in your setup section and enable calls, setup as to re-direct to voicemail after say 5 rings, enable ring.

unfortunately without model and year - more detailed directions cannot be provided...

Your issues is forwarding and message programming, you need to call the tech in that handles programming of the system.

Remove the battery and allow the set to phone to reset. Now check for the ringer setting at teh back of the base phone to be set to the maximum rings, there can be three settings.
Some times this is also set on the menu.
Connect and test the timing to confirm

Please check if any call divert or incoming call barring (found at settings menu) are actives .

Sounds like you need to set the call forward no answer to the VM pilot DN for the set with the new mailbox.

Does the phone actually ring 3 times. I was having the same problem I was informed that it was not even going to my phone. When I had this same problem T_Mobile could not fix the problem using the 3 g network. If you shut off the 3g feature your problem will go away

do a master reset and clear of the phone

i would got into your voicemail settings and check to see if you have it set to ring once then straight to vmail.. i'm not sure how your phone is set up completely but i would assume you can adjust the amount of rings before vmail picks up.. is this phone new to you?
hope this helps..

get your mailbox number then type in **61*44then mailbox mumber*11*then a two digit number between 00 and 30 (seconds delay).
