‘Call Failed’ error when making calls

This issue has the following symptoms:

 

For version 1 Sure Signal (the one with four lights on the front):

  • Lights one, two and four are all solid
  • Incoming calls, texts and internet all work correctly
  • When making a call on a registered phone, the error ‘Call Failed’ or similar is displayed

 

For version 2 Sure Signal (the one with 3 lights on the front):

  • The power and system lights are both solid
  • Incoming calls, texts and internet all work correctly
  • When making a call on a registered phone, the error ‘Call Failed’ or similar is displayed 

 

For version 3 Sure Signal (the plug in version):

  • The power, internet and service lights are all solid and the in use light is either solid or flashing
  • Incoming calls, texts and internet all work correctly
  • When making a call on a registered phone, the error ‘Call Failed’ or similar is displayed


Troubleshooting steps:

Check for planned maintenance:

Planned maintenance can cause periods of downtime, so check the forum for any planned maintenance. If there is, this will be announced at the top of the Sure Signal forum.

 

Reset your Sure Signal:

 

For versions 1 and 2:

  1. Hold in the reset button until all lights go solid
  2. Pull the power lead out with the reset button still pushed in
  3. Continue to hold down the reset button and reconnect the power lead
  4. Wait for all lights to come on and then release the reset button

 

For version 3:

  1. Locate the button on the base of the box next to the Ethernet ports.
  2. Press and hold the button for approximately 30 seconds.
  3. Once the lights come back on, release the button.

 

The Sure Signal will be back online in around 1 hour.

 

If you’re still unable to make calls, there may be a compatibility issue with your Sure Signal and your location information (also known as SAC/LAC compatibility).

A SAC (Service Area Code) connects to a mast and is used to determine the rough location of where a call’s made. It's needed for the emergency services to know where a call was made from.

 

As a Sure Signal can be used anywhere in the country, it doesn't automatically come with a SAC. The SAC is generated based on the postcode you enter when registering your Sure Signal and it's created based on the nearest cell to your location.

In order for calls to be made, they must go over an MSC (Mobile Switching Centre). If the MSC doesn't hold the SAC for your area on its database, the call will fail.

 

The MSCs should now hold all SACs for Sure Signal calls. For anyone who is still affected please post in this thread and we can look into it further.

 

Thanks,

 

Jenny

Worth trying again.

 

It looks as though the problem may have been sorted  at about 4:15pm, or thereabouts...

Hi everyone

 

Thank you for your posts.:smileyhappy:

 

I understand that we rely more on our devices and when this is compromised it is frustrating, please can you let me know if you are still experiencing difficulties after a factory reset.

 

Factory Reset
Hold down the reset button until all the lights show (about 30 secs) keeping the reset button held down, remove then reinsert the power lead, once all lights display release the reset button. The Sure signal will come online in around 1 hour.
 
Many Thanks

Help!

 

Hi Everyone, I am getting the dreaded call failed problem with my Sure Signal. Here is some information about the problem and where I am with it:

 

I've been a happy customer of my Sure Signal for over a year now and never really had any issues with it until about 2 weeks ago. All of a sudden the Sure Signal wouldn't connect to Vodafone (only a solid power light and nothing else). After some troubleshooting I managed to get the device to connect back to Vodafone, this required a facotry reset and configuraton of my router. After 24 hours everything appeared to be back to normal, all the lights were on the Sure Signal and my phone was connected, now however when I try to make a call it just fails. It appears to make one ring on the phone I am calling before just beeping and cutting off. To try and troubleshoot the issue I de-registered the device from my account, left it 24 hours and then tried to re-register, unfortunately there appeared to be a problem with the web page as I kept getting a WebLogic stack trace from the server going through the registration process. I proceeded to ring Vodafone and got put through to their technical support. The woman on the phone re-registered my device and then resynced the Sure Signal, I then factory reset the box as she asked me to and wait for 6 hours. Unfortunately I am still having issues. Please can one of the members of the tech team on the forum try and sort this for me. I don't get any signal bars at my home address and rely on the Sure Signal so I can make and recieve calls.

 

My Sure Signal s/n is 21230492478

 

Many thanks in advance,

 

Chris

Hi chrisayres

 

Thank you for your post and the additional information.:smileyhappy:

 

All the results look present and correct so this would appear to be a Service Area Code (SAC) issue, so we can get this rectified please follow the Private Message I have sent to you, once we have your response either myself or one of the team will be in touch as soon as we can.

 

You can find your PM inbox here.


Many Thanks

This is getting tedious. I rely on Sursignal and i think by now Vodaphone should be at least acknowledging a problem and not just suggesting rebooting the broadband router. How do they think we are sending these messages?
