  • Each participant in a conference call is considered one of the concurrent calls.
  • If your organization will need to record a large percentage of calls (~40%), you might consider purchasing a larger appliance than you would have based on the maximum concurrent calls (or the E540 over the E530).
  • Please contact Digium Sales if you plan to:
    • Use “Ring All” features to simultaneously ring a large number of phones for calls, queues, pages, or intercoms. 
    • Use Presence/Status features with most or all of your users.
    • Use Switchboard queue widgets for large numbers of queues with large numbers of members in those queues.
    • Have more than the maximum users, but are within the maximum concurrent calls.
  • Exceeding Digium's advertised number of maximum concurrent activities or conducting other concurrent activities not listed above can adversely impact call quality.

VoIP Protection

Want to protect your switchvox environment? A Session Border Controller (SBC) is the right way to do it!

Businesses connecting their infrastructure to a SIP Trunk, or VoIP connection, require a Session Border Controller (SBC) for security, interoperability and transcoding. Often times, businesses will forget the importance of an SBC when switching from their legacy phone system to VoIP and simply use their existing firewall for protection, and make a huge mistake!

  • A typical firewall can only protect your data network and as soon as you as you open it up to the internet, which is how you connect to VoIP services, the entire network is exposed.
  • The other pitfall of using your existing firewall, instead of an SBC, is that phone calls may not connect or there will be audio issues. An SBC will automatically do the call translations for you, with the built-in interoperability features and also translate the audio with built-in transcoding capabilities.
