  • Ribbon SBC Core
  • Ribbon SBC Core license
    • A valid license from Ribbon is required to enable functionality on Ribbon SBCs. Each SBC license provides a base set of capabilities to allow enabling and adding of additional features and capacity, as required.
  • Public IP addresses
  • TLS certificates for SBC Core
  • Google Workspace and Domain
    • Google Voice Premier license for the users
    • For more details, contact Google Support

...

To deploy Ribbon SBC Core standalone instance, refer to SBC Core 9.2.x Documentation

Ribbon SBC High Availability

To deploy Ribbon SBC Core in HA mode on different platforms, refer to SBC Core Software Installation and Upgrade Guide

Info
titleInfo

During this interop, SBC Core HA was installed on VMware platform by following the procedure described in Installing SBC Application in High Availability Mode.


Tip
titleTip
  • After successful installation, ensure the time on both Active and Standby SBCs is in sync.
  • NTP Sync verification:
    • Run the command 'timedatectl' to check if NTP is synchronized.
    • File /etc/ntp.conf should contain the IP of the NTP server that you have configured during installation.

...

  • For TLS to work, a Trusted CA (Certificate Authority) is required. For this interop, GoDaddy is used as a Trusted CA.
  • Add an entry in the Public DNS to resolve Ribbon SBC Core FQDN to Public IP Address.
  • In the trust store of the SBC, ensure you have the following certificates as part of the root certificate trust.
    • GTS Root R1
    • GlobalSign R2 Root CA (if required)
Info
titleNote

Refer to Google Voice SIP Link documentation for other compatible CAs.

The following items should be noted in relation to this Interop - – these are either limitations, untested elements or useful information pertaining to the Interoperability.

  • Short Code calls are not supported on Google Voice clients.
  • After an SBC switchover, the SBC takes around 45 approximately 12-16 seconds to establish a new TCP socket connection with GV for sending first SIP OPTIONS (with OPTIONS "pathcheck" profile interval set to 10 seconds) over TLS.  HenceHence, all the calls, including in-dialog messages initiated from GV the Google Voice end towards PSTN during this period, will be failed as fail because GV does not initiate any new socket sockets for a TLS connection , unless a new call/In-dialog request from PSTN end is initiated towards GV over TLS. 

These issues will be addressed by GV/Ribbon in their upcoming releases.
