How would the integration of 3CX smartphone clients into the hotel environment of the 3CX. I mean shipping a wellcome mail at checkin and changing the password at a checkout. The guest decides whether he is calling via GSM or via WLAN. Message Waiting was yesterday, message could be sent over the chat to the client. No hotel would like to invest more in phones and gateways today and WLAN is now a must anyway. What do you think about that?
