Voice over IP network call
1 The Digital Telephone IP Adapter user lifts the handset (item A).
Result: The Digital Telephone IP Adapter user hears a dial tone. This
indicates a successful connection to the RLC over the IP network (item B).
2 The Digital Telephone IP Adapter user dials a telephone number, such as
the extension number of host station 1.
Result: The Digital Telephone IP Adapter unit sends the dialed digits as
packets through the IP network to the Ethernet network or Corporate WAN
to the RLC. The RLC converts the packets to the format required by the
host PBX.
3 The host PBX then converts the data to voice and routes the call to host
station 1 (item C).
Note: Item notations in parentheses refer to circled markers in the diagram on
page 38.
