[GER] VoIP @ Arcor does not work

[Tugi2o]

Hi,
i've tried to use 3CX with German VoIP provider "Arcor".

My User-Account:
phone-number like 0987-655432
Username: [email protected]
Password: 777777
SIP-Proxy/Registrar: 0987.sip.arcor.de
SIP-Port: 5060

If 3CX tries to connect, i always get the error:
ClientRegs:nFailure: Registration of sip:0987655432%[email protected]:5060 has failed; reason=Forbidden

How must i change my settings???

ClientRegs:nSuccess: Registration of sip:[email protected]:5060 is successful
