SIP account; no register sent in case @ contained in userID
I have a sip-account that looks like +43.....@somedomain.at , so looking like a phonennumber (and of course, it is). The somedomain.at is integral part of the userid.
If I enter this into the account config no sip:REGISTER is sent. If I keep the config as it is but omit the @ the registration is initiated, but of course it failes because of the wrong userid.
