Brief Description
Voice over IP is increasingly replacing analog and ISDN-based transmission technology. This creates
the need to integrate existing ISDN private branch exchanges (PBX) in the new IP environment and
to also provide the ISDN service in an all-IP network.
The ISDN-SIP Gateway 400 provides 4 S
This allows up to 8 simultaneous calls over the IP network. The connection can be made via both a
VDSL2/ADSL2 link and also with an upstream modem/router (e.g., SHDSL) via the WANoE interface.
The provision of a number of supplementary services such as CLIP, CLIR, COLP, COLR, and CFx enable

as a router for data services over the same DSL line.
