Is SBA or Direct SIP a requirement for Enterprise Voice RRS feed

  • Question

  • Hi

    Some of  our sites may not have an SBA  installed locally or no Direct SIP connection. So they will not have PSTN access.  My question is, could we enable those remote users for Enterprise Voice policy so that they can use CallForwarding, SIMRing and other features available in Enterprise Voice. In other words, is a Direct SIP or SBA a must for enableing Enterprise Voice for users. Thanks in advance.

  • A local SBA or PSTN connection is not required to enable a user for EV.  You can easily route the users in the branch office out a gateway in a different office.  The SBA will provide local PSTN access and voice resiliency in the event of a WAN failure and the user cannot reach their associated FE pool.  As long as their is some connectivity in your environment to the PSTN, then you can route calls accordingly.

  • Hi,

    You can enable the those remote users for Enterprise Voice without SBA and PSTN connection. The SBA just provides registrar and mediation features for Branch users. It doesn't influence users to be enabled Enterprise Voice.
