The PBXs are connected to the Cisco IOS voice gateways by E1QSIG trunk circuits. The Cisco IOS voice gateways “extend” the E1 QSIG trunk circuits with VoIP, using the H.323 protocol.• A Siemens HiPath 4000 Release 1 PBX and a Siemens Hicom 330E Release 3.1 PBX were each connected via E1 QSIG trunk circuits aCisco IOS voice gateway. The two voice gateways were connected via IP over Ethernet, and configured for VoIP using H.323. End-to-end calls were placed between the PBXs to exercise and test basic calls as well as QSIG supplementary services such as call transfer, callconference, and call forward.• Using the Siemens PBX configurations and Cisco IOS voice gateway configurations in this application note, successful toll bypassintegration was achieved. This includes basic call, call transfer, call conference, and call forward, with some limitations on Caller IDfeatures during transfer scenarios. These limitations are detailed in the following sections and all were found to be inherent to theSiemens PBXs. Thus, H.323 toll bypass introduced no new restrictions to the available features or performance.
