Incoming Calls from a 33 Number

Hi, I am not sure if I've raised this problem before on this forum, however I did not find any other posts about this on the forum.


So I ported my landline, and have the FreshPHONE service running through a Huawei B315 modem and using my existing cordless phones, and have not had any issues with operating the service like this.


However, at least once or twice a month, I receive calls from a 33 number, which dials at very random times. What I usually do is let it ring, and it stops after calling in once.


This morning this 33 number called in at 5:45am (and woke me up) and I tried declining the call once. It then persisted calling in (with me not answering it) several more times, every few minutes for the next 20 minutes, until it stopped by itself.


I'd be lying if I was to say that this was not annoying to say the least.


But above that, is there a reason why this keeps happening every month?


Any explanation or solution would be highl appreciated.


I think this is a form of SIPvicious attack since I see no record of any calls during that time period. Please could you try change the SIP port on the phone device you are using, remember that the SIP register port needs to still be 5060 but there could be a setting for the Phone's SIP port as seen below on this Yealink.



Hi Fresh Man, not entirely. I received one about a week ago, and all I do is to let the phone ring until it stops.


But this time it only happened once, and didn't repeat itself like it did before.


I'm happy to leave this little glitch, as the platform works with the analogue phones I have.


I reported the ghost calls hoping that there could be a solution found that didn't need me to consider having to buy another handset (which may or may not solve the problem).


I like the setup, calls are clear and I never had one issue (apart from the previous numbers I didn't know calling the 0860 number), but that has also since been fixed.


I'm just afraid to introduce something else in the mix that might make things not work.


So for now I will live with them I guess.


Thanks.

I'll try and see if there is a setting like that on my device and will attempt to make the changes later this evening.

I spoke too soon. This 33 number is still calling in at 6:30am, and I tried looking at the call log to see if it even shows up, and it does not even register on the Incoming Call history.

Hi Fresh Man,


Thanks for the clarity. It's not really a trainsmash, since I know it's a minor glitch.


So all is well.


Thanks again for all the help.

Hi Odwa,


Please advise what brand and model of the cordless you have. 


Thank you. 

Hi there, I use the Panasonic KX-TGA131EX (3-handset) cordless phones.


As stated, the phones work just fine when setup via the Huawei modem. It's just this number 33 that keeps on dialling in every now and again.

Hi Odwa


Yes, it is not a real number, it is just a packet of info sent to the phone which causes the phone to ring as the phone does not know what else to do. Which router do you use?

Hi Odwa


Did you manage to find the setting?

Hi Fresh Man, just been having some issues with intermittent internet for the past day or so, but that seems to have been fixed, and I will check today.


Just for clarity, I must look for the setting within the Huawei B315's settings, correct?

Hi Fresh Man,


It's the Huawei B315 LTE modem. It's the black one, so I guess it's the slightly older model, since I think there is a newer Hauwei B315 modem.

If you are using the router as an ATA adapter then yes.

Hi Fresh Man,


Sorry for the delay, but I've just been busy on my end.


So I went through the Huawei B315 LTE modem settings, and only found this page (under VoIP settings) which had any configurable port settings.


The settings in my screenshot are as per the settings that are described on this site, on:

"How do I set up a Huawei B315 with my Analogue phone?" found at this link: http://help.freshphone.co.za/support/discussions/topics/17000005021


And as stated, everything works just fine, apart from the random 33 number that dails in ever so often.


So which of the port settings from my screenshot should I change, and what should I change them to? And also, will this leave my service still able to make and receive calls, as it has been?


And most importantly, will it resolve that dialling in from that random ("ghost") 33 number?

Hi Odwa


Another device will experience the same issue if used with a router that is not securing your network. So please don't try buying another handset
