Compared to Sipgate, the web interface appears very basic:
* No contacts list, no ability to have contact names added to call histories, no click-to-dial
* No web access to voicemail, no ability to add contact names to voicemails
* No phone access to voicemail, you can change your outgoing message but NOT retrieve incoming voicemails at all. The ONLY way of getting voicemail messages is having them emailed to you
* No sending SMS from your account web pages. There is a separate web page for sending SMS which needs your username/pwd to be entered each time.
This is really awkward for me - I have a regular need to log on via web, listen to voicemails, and transcribe them into SMS and send from the VoIP account to mobiles in a contacts list.
