Ip phone 7940 is restarting

When mobile extension user logged on call manager, ip phone 7940 itself restarts and the user can not get a call from outside.(PBX,POST,v.s)

Are you refering to extension mobility? When user a logs into phone A, phone A reboots, and loads the EM profile. So the one time reboot is part of how EM works.
Check to see if the EM profile has any partition in the DN, then that partition needs to be in a CSS that is configured under the Gateway (incoming calls) section.

I have the iphone 4 and PC with Windows Vista Basic. When I bought my iPhone syncs with iTunes on my computer, but now when I try to sync it tells me that Mobile Device Service was closed and I can not synchronize the phone. Try restarting Mobile Device Service and uninstall and reinstall Itunes but still giving me the same error.

I get a message no sim card, yet my sim card is in phone. I restarted it, no change. Any ideas?

Anyone know how to fix a sim card issue? My iPhone gives me a message "No sim card" - yet the sim card is in phone. I restarted the iPhone, no change.

Try to "clean" the sim and put it again into the phone.

Strange email problem; it started only loading unread emails, but from 3 months ago. It is now loading new emails too, but no emails in the past month, read or unread. It's gmail, set up through the phone, I've restarted restored

Strange email problem; it started only loading unread emails, but from 3 months ago. It is now loading new emails too, but no emails in the past month, read or unread. It's gmail, set up through the phone, I've restarted restored and updated firmware, deleted the account, anything I could think of, but it's just not accurately downloading the most recent emails.

The answer is very simple: You were not the original owner of the phone. Target sold you a phone that had been returned. You can verify the date of the original sale here: Apple - Support - Check Your Service and Support Coverage. I suspect you will find that the warranty expiration date is not one year from the date that you bought it.

hi there i have an iphone 4 i think it started installing ios6 and did not complete and now my phone refuses to restart it just keeps on rebooting

Try forcing the phone into recovery mode. Disable ALL anti-virus & firewalls first.
Turn your phone off, then:
Leave the USB cable connected to your computer, but NOT your phone, iTunes running, press & hold the home button while connecting the USB cable to your dock connector, continue holding the home button until you see “Connect to iTunes” on the screen. You may now release the home button. iTunes should now display that it has detected your phone in recovery mode, if not quit and reopen iTunes. If you still don’t see the recovery message repeat these steps again. iTunes will give you the option of restoring from backup or as a new device.

Re: i tried updating my iphone to a new verison but after the update the phone is not restarting, just the apple sign is showing up on the screen. what is the problem?
I have tried the above fix and iTunes crashes giving error 27 after trying to load the iPhone firmware.
I have booted my phone in DFU mode and this has made no difference.
My mac is up to date.
My iTunes is up to date.
All i tried to do was update my ios as i have been unable to make calls or send text's all day.
Do you have any other suggestions as my phone is no good to me now.
Many thanks,

Why does my iPhone 3GS keep restarting on its own, and when I move the phone while its restarting, a white screen comes up and then it takes a while to turn it back on!

So i have an iPhone 3GS and when i move the phone while its restarting, a white screen shows up, and sometimes i need to punch it to turn it on. HELP i dealt with this problem for months and im sick of it! HELP ME!!!!

Sounds like hardware failure, called boot loop. Call Apple and or go on apple.com and make Genius Bar appointment to have your iphone reviewed by a Tech. Provided you iphone shows no physical or liquid damage they will take care of you, or if you have Apple Care Plus

Click here and follow the instructions if you can. If you can't unlock it yourself, take the device and its original purchase receipt to a physical Apple Store and see what they say.

HT1688 Since I've upgraded the IOS to 7.0.2 on my iPhone 5, my phone will randomly restart itself. Is there a fix for this?

Since I've upgraded the IOS to 7.0.2 on my iPhone 5, my phone will randomly restart itself. Is there a fix for this?

Howdy there Tuna241,
Thank you for using Apple Support Communities.
It sounds like your iPhone is restarting unexpectedly after the update to iOS 7.0.2.
I recommend the steps outlined in the article named:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Regards,
Sterling

HT1766 I've just purchased an Iphone 5c. I have chosen the restore from iCloud and the phone has now restarted to complete the restore. It has been 3 hours and the progress bar has not moved.

I have chosen the restore from iCloud and the phone has now restarted to complete the restore. It has been 3 hours and the progress bar has not moved. I have now tried to reload again by holding the sleep etc, to no avail

If all you want is your old photos, you could backup your new phone using iTunes, then restore it from your iCloud backup, import the old photos to your computer, then restore it from the backup your made in iTunes returning your newer data to your phone. If you want your old photos on your phone, sync them there from your computer using iTunes. The process would look like this:
Connect your phone to your computer, when it appears in iTunes on the left sidebar right-click on it and select Transfer Purchases; right-click again and select Backup.
Disconnect from your computer and go to Settings>General>Reset>Erase All Content and Settings to return it to new
Go through the activation setup, choosing to Restore from iCloud backup. Make sure your phone is plugged into a charger and has access to wi-fi as this can take hours to complete.
When complete, without connecting your phone to your computer, open iTunes and go to Preferences. On the Devices tab check "Prevent...from syncing automatically"
Now import the old photos to your computer (see http://support.apple.com/kb/HT4083)
When done, open iTunes, right-click on the name of your phone on the left sidebar and select Restore from Backup, choose the backup you made in step 1.
Go to the Photos tab and select the photos you want to sync to your phone and sync.
