You can occasionally experience situations where you can't place calls to certain numbers and the reason behind this is usually the number being blocked by one or more providers.
Toky is usually never informed of the list of numbers in the no-call list because normal accounts are never affected by this blockage.
Another less likely reason to encounter this problem is when you attempt to call numbers with abnormally high cost-per-minute prices. Calling to special numbers can be affected by this situation.
If you are being affected, and you have reasons to believe it's a mistake, please get in touch with our Support Team.
