SERVICE INDICATOR TRANSLATIONS
Some types of routes use an External Service Indicator (ESI) to identify the type of user
information being sent. The ESI is handled by ISPBX as follows:
-
For an incoming call. The External Service Indicator (ESI) received over a route is
translated into an Internal Service Indicator (ISI). The ISI consists of an Internal Service
Identification Code (ISIC) and an Internal Basic Service Category (IBSC). The ISIC, if
available, is passed transparently to the internal port. The IBSC is used for the
determination of compatibility within ISPBX.
-
For an outgoing call. Information passed over the route must be accompanied by an
External Service Indicator (ESI). The Lower Layer Compatibility (LLC) from the user port
(if applicable) is incorporated into the ISIC. The ISIC and IBSC are combined into the ISI
which is translated to an ESI.
The list below shows the route type and the name used to identify the ESI.
