Hello everybody,

I'm experiencing quite a strange issue with some voip carriers when I
try to call my own GSM cell phone, using international route (I'm in
switzerland).

With some budget routes (value route from voip.ms for example), I get
a fast busy tone, congestion message, or nothing at all when I try to
call my cell phone number +4178NNNNNNN. I can call swiss landlines
numbers, or even other cell phones without any problem.

voip.ms support wrote me that my phone number is "showing as premium
number". To avoid fraud, there are no routes to this kind of number,
so the call cannot be made.

I'm using a regular cell phone account, and I never ordered premium
services. My number lookis like every other cell phone number out
there. I never experienced any routing problem with my cellphone,
before I tried to call it from voip providers.

Can someone explain me what's this "premium number" thing about my
very regular and usual cell phone number ? How can I change this ? As
voipms carrier got the information from some database, who should I
ask to remove my number from the list of premium numbers ? I guess I
should ask my telephone operator, but of course nobody's is
understanding what I'm talking about when I call the support...

Thanks a lot, best regards, Julien

Hello,

+4178 is clearly Switzerland mobile, not a premium number:

Chances are there is nothing wrong with your number. What your provider
is saying is probably an excuse for a badly performing route to mobiles.

Note that usually termination providers will maintain different routes
for landlines and mobiles for the same destination country. In many
cases, esp. low cost providers, the landline route will perform better
than the mobile route.

Best regards,
Vlasis Chatzistavrou.

There has been some real stupid stuff going on in the inter carrier market recently.

One of them was to attach a massive premium €2.50 per minute to calls to Switzerland sunrise mobile for example.. This was only if your CLI was of certain countries or invalid.


I don't know anything about voip.ms but perhaps this is whats happening here, they could be just flagging swiss mobile as a problem due to the potential of landing charges of 2.50 euro in excess of what they should be paying and perhaps they're caller ID into the swiss pstn is less than reliable hence they could fall foul of this.
