Solution

‘Call Failed’ error when making calls

Retired-George

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

Hi dserazet,

 

Please try the Sure Signal at an alternative address. This will help rule out any hardware fault with it.

 

Let us know how testing it somewhere else goes.

Thanks,

Hi jona,

 

Thanks for posting.

 

There seems to be some quite long times in the traceroute.

 

So we can help further please follow the steps below.

 

Your speed test results from here.

Your ping test results from here.

Your external IP address from here.

This will help us get the quickest possible resolution for you.

 

We also advise to login in to your router settings and make sure that the IPSEC box is ticked also.

 

Cheers,

 

Laura 

Laura,

 

Please do read my post. I had already provided that info, I have paid £100 for something that is not working and costing me money on my landline.

 

The test results asked for. (ping etc.) were all given.


I have now lost another 24 hours or so of connectivity. Could you please send me some vodafone vouchers for the time lost so far. Please do not tell me i need to speak with customer services. Please do this on my behalf.

 

I will do the IPSEC check also. Please advise how i get into router settings.

 

Thanks Jon

Hi jona,

 

The results are all fine.

 

Please speak with your ISP to get instructions on how to enable IPSEC.

 

Thanks,

this is really frustrating. the phone used to work fine and it now does not. I cannot see Ipsec settings on my router settings which i have gone into.

 

you have had the results of the other tests. what is the problem. I have given vodafone £100 and my phone does not work at home.

 

please help. could it be an iOS upgrade i have done. My phone has not changed

Hi jona, 

 

If you speak to Virgin they can check that IPSEC is enabled. 

 

I've checked your traceroute and some of the steps are far too high. These need to be below 200ms, one of your steps is over 600ms. 

 

This points to latency on your internet connection. This is something Virgin should be able to help with. 

 

Thanks, 

 

Kay
