Yes and you don't need to register different source IP addresses for each product or create different SIP accounts. All you need to do is choose Voiplid MIX product from the product list during registration. Voiplid MIX allows you using all three VoIP products having a single account. The only specifics is the selection code (prefix) which is 9991 for Standard, 9992 for Premium and 9993 for Premium Plus.
