We recently added support for 1and1 to our popular PBX Express tool. Now you can fire up a 3CX instance, fully configured, in minutes and have it running in your own 1and1 account. This is ideal if you are already a customer of 1and1 and are hosting your web server there, or if you are a 1and1 reseller.
The process is easy – you will need to purchase at least one cloud server in your account and then enable API access. See the full step by step guide here.
The general interface of 1and1 is easy to understand and you have access to all the monitoring, backup, security and firewall features through an easy to understand web interface.
