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.

User's Manual
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.
