This document gives a brief overview of the different soft phone options.  You may also want to read our article on how to Configure a Softphone.Important Note: Softphones or applications that register behind a Proxy or SBC (such as ReachUC and Microsoft Teams ) are not recommended or supported for call centers agents.To clarify, the Proxy handles registration even if the soft phone or remote application is offline. The PBX will still try to deliver calls to Proxy or SBC, varying SIP responses from the SBC will skew many call center statistics. If the agent is always online, many of the issues described above can be avoided by properly logging in and out of the queue. Keep in mind, loss of internet or a routine restart without the agent logging out will negatively impact statistics like missed calls.SkySwitch – Attendant ConsoleThe Attendant Console is a powerful feature connecting your PBX to a Web UI; allowing you to manage Presence, Transfers, Parking, and Queues.  This is NOT a softphone but works in conjunction with your existing physical or softphone.  Available upon request from SkySwitch support, please specify which on which domain/s this will be activated for.https://skyswitch.elevio.help/en/articles/62ReachUC - Various Options ReachUC allows users to interact with the PBX through an intuitive user interface. The app offers easy access to make calls, send/receive SMS, check voicemail, view phone and PBX contacts as well as view call history and view advanced PBX features including PBX presence.  ReachUC offers mobile apps for iPhone and Android, a Browser-based webRTC client ( These three versions are not recommended as a desk phone replacement, and not suitable for call center needs.)ReachUC also offers a Windows and Mac application that uses SIP messaging natively. The 'Native' SIP application is more suitable as a dedicated softphone, but like all software-based phones they can be hindered by computer hardware or other software running on that computer.https://www.reachuc.com/SkySwitch – Dialplate  (Available in the SkySwitch store)Dialplate is a Windows Only Softphone and Attendant Console Solution that can be purchased through the SkySwitch Store featuring 4-16 lines over 3 accounts.
