The network that routes the host-controlled call is transparent to the user. Both
VoIP and PSTN calls present the same dialing requirement, as described on page
31.
Voice over IP network call
1 Remote Gateway 9150 user 1 presses the host call appearance key
(item A).
Result: Remote Gateway 9150 user 1 hears a dial tone. This indicates a
successful connection to the RLC over the IP network.
2 Remote Gateway 9150 user 1 dials a telephone number (such as the
extension number of host station 1).
Result: The Remote Gateway 9150 unit sends the dialed digits as packets
across the Ethernet network to the RLC (item B). The RLC converts the
packets to the format required by the host PBX. The host PBX then
converts the data to voice and routes the call to host station 1 (item C).
PSTN call
1 Remote Gateway 9150 user 3 presses the host call appearance key (item
1).
Result: Remote Gateway 9150 user 3 hears a dial tone. This indicates a
successful connection to the RLC over the PSTN.
2 Remote Gateway 9150 user 3 dials the telephone number, such as the
extension number of host station 3.
Result: The Remote Gateway 9150 unit sends the dialed digits across
ISDN BRI through the PSTN, through the host PBX to host station 3 (items
2, 3, and 4).
Note: Item notations in parentheses refer to circled markers in the diagram on
page 30.
