Note that XS4ALL is NOT working if a mobile phone number is included in a ringgroup. XS4ALL gives the status that the line is connected as soon as the mobile phone rings. This means that 3CX thinks the call is accepted on that line and the other phones in the RG will stop ringing.
CallVoip.nl offers good and inexpensive lines, no problem with this problem.
