Hi,

I'm using a cordless Panasonic phone with caller ID and I've noticed that some 021 numbers (assuming they switched networks but retained the number) on spark show up with 00 in front of the 021 on caller id

Eg 00021

This is only for two specific numbers and they are both 021 numbers. All the other numbers show up normally eg 027, 022, 021. Is there something wrong with their sim cards or mobile phones or is it just a quirk of the system when there number was changed over. The reason I am wondering is that I am blocking international numbers with a 00 number block and those two get blocked with all the other intl calls.

Thanks

I think he means a setting on your cordless phone - I remember a setting on my cordless handset had to be adjusted too to remove an extra leading 0 on all numbers, but I can't remember where it was.

No that's not right because it isn't a problem for the majority of numbers. It's only two specific mobiles that show up like this.

Why would it add two zeros to two random numbers (actually not that random because they are both 021) and leave all the others untouched?

Because of the length of the numbers and logic of the cordless phone in how it treats them

Oh ok. Thanks. The Panasonic cordless must be adding 00 to 11 digit mobile numbers and leaving the 10 digit ones alone.

That's the phone. I can't see any setting that would remove 00 from long numbers though...

You cant, its a bad assumption they made when implementing the display of an antique protocol that wasn't properly made to handle international numbers. They seem to guess based on the length of it what it is.
