  • It has become more and more common for hotels to offer broadband connectivity. Softphones are the perfect tool for the road warrior who needs to check voice mail, or speak to the home office. Our softphone will provide full feature functionally through a software application.
  • Context Sensitive help is available for the softphone. No more users guides that are all too often lost. Setting up the application is easy and fast.
  • Each softphone has a built in call log for incoming and outgoing calls.
  • Through the connection to your email address book, you can contact any of your clients with a button depression.
  • Station status can be assigned to invoke rules for your call coverage. When you are out of the office, you may wish your phone to be answered in a unique way.
  • SIP phones are widely accepted and are required in every tender. The SIP protocol can handle any type of media, audio, video, games, messaging etc. IT managers and security managers will punch the holes through their protection facilities to allow SIP to go through. SIP phones are relatively inexpensive, they are available from multiple vendors but they will usually provide basic functionality. SIP is being used as the preferred interface to IP Telephony service providers.
