Notes:
• The capacity figures listed in the table below are accurate at the time of
publication of this document. However, these figures may change due to a later
software update. For the latest figures, please contact your AudioCodes sales
representative.
• The maximum number of SBC signaling and media sessions are specified in the
installed Software License Key, which defines maximum figures for each one
separately.
• The maximum number of voice transcoding sessions is specified in the installed
Software License Key.
• Registered Users indicates the maximum number of users that can be registered
with the device (i.e., in the device's registration database). This applies to all the
supported applications.
• Regarding signaling, media, and transcoding session resources:
√ A signaling session is a SIP dialog session between two SIP entities, traversing
the SBC and using one signaling session resource.
√ A media session is an audio (RTP or SRTP), fax (T.38), or video session
between two SIP entities, traversing the SBC and using one media session
resource.
√ A gateway session (i.e. TDM-RTP or TDM-SRTP) is also considered as a
media session for the calculation of media sessions. In other words, the
maximum Media Sessions specified in the table refer to the sum of gateway
sessions and SBC sessions.
√ In case of direct media (i.e., Anti-tromboning / Non-Media Anchoring), where
only SIP signaling traverses the SBC and media flows directly between the SIP
entities, only a signaling session resource is used. Thus, if a greater signaling
session capacity exists than media, even when media session resources have
been exhausted, additional signaling sessions can still be handled for direct-
media calls.
√ For call sessions requiring transcoding, one transcoding session resource is
also used. For example, for a non-direct media call in which one leg uses
G.711 and the other leg uses G.729, one signaling resource, one media
session resource, and one transcoding session resource is used.
