The Dialogic® Diva® System Release software supports basic call services for the available switch types. In addition to this, it offers supplementary services for the following switch types:
Q.SIG support is available for the derivatives ETSI-SS, ECMA-QSIG, and ETSI- QSIG. Thus, the Q.SIG switch type can be used with any PBX based on one of these derivatives. Q.SIG has been tested with a number of various switches, for example, Hicom 150, Hicom 300, Lucent Definity, Alcatel 4200, Alcatel 4400, Ericsson MD 110, Nortel Meridian, and Nortel M65xx.
The table below gives a detailed overview of the supplementary services supported by the switch types listed above. The availability of supplementary services also depends on your PBX. For detailed information on supplementary services supported by your PBX, contact the PBX manufacturer.
