The Telesis PX24U Hybrid IP PBX provides hundreds system features, system
parameters, and user services. If it is desired, these may be activated or deactivated.
With these programmable features and services, the PX24U make traffic management
highly efficient and versatile. The convenience of dealing with all-in-one system
software Xymphony allows the user to support as many features as desired, up to the
maximum capacity. Another aspect of the system`s software is an advanced algorithm
for creating routing tables.
Many of the user services are applicable for SIP calls with using the basic SIP
supplementary services such as Invite (call hold), call forward and call transfer (with
refer method). Similarly, these are also applicable for H.323 calls with using the basic
H.450 supplementary services.
Furthermore, Telesis proprietary xSIP (eXtended SIP) protocol allows value added
services of the DTS digital telephone sets also to be functional over IP.
For ensuring the easy and fast programming of the PX24U, each programmable
parameter is set to a default value. The standard default values are carefully selected
and optimized for a wide range of customers` requirements. Thus, the flexibility does
not bring a complexity.
