How can I change the ring back time for a call on hold? My phone currently only keeps a call on hold for 30 seconds before it starts ringing back. Drives me CRAZY.

Standard Android procedure

On your phone's keypad, dial (or tap):

• * * 61 * 13065206245 * * number of seconds #
• The number of seconds must one of these numbers: 5, 10, 15, 20, 25, or 30
• For example: To set the ring time to 10 seconds, dial: **61*13065206245**10#

..

You need to enter the programming mode from the default EXTN usually 20 or 21 and change the timings of the ring counts, normally shown in seconds, adjust to 30 secs which should give you the amount of rings you need if not just go back and adjust the ringing counter seconds up until you find the length of time that suits your needs.

For all of you that want a real answer here ya go. This isn't something you can change on your phone this has to be changed with your service provider. If you are with AT&T, like I am, then this is the solution for you (link of where I found it below as well). 1. enter *#61*11# and press send/talk on your phone.
2. write down the number your calls are currently forwarded to (usually +1401#######, but not always). this is your voicemail deposit number.
3. decide how long you want the phone to ring in 5 second intervals. the maximum time is 30 seconds. i'd recommend 25 seconds or less, as using 30 may cause you to be billed for a minute of airtime each time someone is forwarded to voicemail.
4. now enter **61*[number from step 2]*11*[number from step 3, use 2 digits]# and press send/talk.

example
voicemail deposit number is +14015551212
you want it to ring for 20 seconds
you would enter **61*+14015551212*11*20# and press send/talk.

if you have trouble with the above procedure, you can always call customer care at 800-331-0500 to change it.
OR QUESTION: How can I adjust the number of times my wireless phone will ring before the caller goes to voicemail? ANSWER: Contact Customer Care at 1-800-331-0500 or dial 611 from your wireless phone to change the amount of time your phone will ring before going to voice mail. The adjustments made by Customer Care are based on the traditional ring heard by the caller, not the unique Ringtone you hear from your phone. I just wanted to add that increasing the ring length to 30 seconds will not cause you to be charged a minute should the caller go to voicemail. This was confirmed by an AT&T technician.

To change the hold recall timer on a prostar 816 you first need to be at a display set (doesn't matter what the extension number is).
with the handset down enter #20 the screen should say MMC DISABLED
enter in 1 2 3 4 1 # (that enables programming)
The code for hold recall is #52
enter in your hold recall time in sec. and in a 3 digit format. i.e. 30 seconds = 030 a minute and a half is 090 and so on.
press # when finished

1) With the phone in standby mode, press the menu/clock key three times.
You hear “Ring time” and the current ring time ([2 ], [ 4], [6 ], [T ] Toll
saver), and it is displayed on the main base. Then you hear the guidance for setting
the ring time.

2) Press the volume/select/ or up or down arrow key until the desired ring time appears.

3) Press the set key to select the new ring time. You hear a confirmation tone, then
the announcement “Ring time” followed by the new ring time. After a few
seconds, the system announces “To set record time, press menu again.”

if it goes to voicemail, means that you have to set the length of rings before voice mail. so you have to contact your service provider, and they can fix it on their end

hope that helps

In system programming, hold recall times are option 200. In the TD's IIRC they are adjustable from 0-240 with 0 being no recall. In a TA series, they have increments of 30-180 seconds or none.

it sounds like the memory battery on the main board is no longer working which means that it'll happen again.

press *94, then press the number of rings you want 1-9. The tone will change and thats it.
