Hello, on the iptel.org website I created an account. Also my own domain is registered and all works fine. I prefer numbers in the SIP-ID. With my own domain, I thought, I can use every number. But that is not true. Every number must start with the digit 8, for example 8555(a)mydomain.de. What is the reason for that? Have I the possibility to change that setting? I can also create aliases, for example 4123(a)mydomain.de and that works fine. But the telephonee sees still the number 8555 from the account name. Any ideas?
