Minanz:

my missed calls are from an xperia XZ too

 

How do i contact the GSP?

We've looked into this and with the examples given they are not reaching our network which leads us to believe the caller or phone is dailling the wrong number. There could be a corruption with the contact details so we are asking customers to get the caller to manually enter the number, rather than using the stored contact details to see if those calls come through. 

@Minanz - I've PM'd you on this, did you get a chance to try this? 

Regards

^POB

Sorry for the delay in responding to your query.  He has tried both dialing the number and using the number stored in the call log both of these methods sometime work and other times they don't.  Earlier today (11.14 am) he tried to ring me using the call log and got a message saying there was no such number, the second time he rang it came through.

@Minanz as @2degreescare has pointed out the calls are not reaching the 2degrees network so the issue has to be on the A party network. Fault investigation should always start on the A party network as well

Ask the person on the A party network to escalate this to the Spark porting team to check SRRI routing (They could have 2 and one is correct and the other incorrect) and they should also run a trace to look at the failed call

This is a very simple check / fix from the Spark side

Apologies i was replying the previous question, however I should have replied by PM.  Will do in the future.

Will go over steps to replicate this issue @2degreescare

Call a 2degrees mobile number from another 2degrees mobile number and let it ring / page for about 10 seconds (Hang up before call is passed to voicemail) then hang up and call back straight away (As fast as possible) then you will hear the message " 2Degrees does not recognise the mobile number you have called check the number and dial again "

If calling from another carrier you should hear the A party network announcement to check the number not the 2degrees announcement a incoming call from off-net  

John 

Minanz: Thanks John, I am still having the same issue but haven't heard back from 2 degrees.

@Minanz Can you replicate the issue I have described above from another carrier? Off-net

I assume you're on LTE to begin with, not 3G?

@SaltyNZ My handset (A party) must be on 3G as it's setting up the call and I am hearing check the number and dial again from 2degrees

John

Minanz: Settings say 2g/3g/4g auto connect. 2 degrees think it could be a faulty sim card.

@Minanz No it's not SIM card related pointless swapping it out

I did not ask you to check network handset settings, Please read my description above how to replicate the issue, Can you test and see if the same thing happens

Yes and no - if you are in LTE whilst (voice) idle and you make an outbound call, then your handset has to first hand down to 3G in order to make the call. Likewise, if the called party was on LTE when called then they also must hand down to 3G. At the end of the call, both handsets will attempt to hand back up to LTE. I suspect if you try to make a call while that procedure is in progress you might find that it could sometimes fail at one end or the other, leaving you with a failed call.

That would explain why you have to make fast successive calls to provoke it, and why it is intermittent, at least for OP. Add to the mix that there are fast and slow CSFB network procedures. But I can't remember whether the handset needs to cooperate to use the fast one or whether that is mediated purely by core & RAN feature support, nor whether the handing back up afterwards is initiated by the network or the device.
