•Although specific gateway router models were used to validate its content, this application note also applies to all Cisco
1700/2600/3600/3700/2800/3800 series Cisco IOS voice gateways.
•This application note provides configuration guidelines for a toll-bypass network using Cisco IOS voice gateways to connect Siemens
HiPath 4000 Release 1 and Siemens Hicom 330E Release 3.1 PBXs. The PBXs are connected to the Cisco IOS voice gateways by E1
QSIG 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 a
Cisco IOS voice gateway. The two voice gateways were connected via IP over Ethernet, and configured for VoIP using H.323. End-toend calls were placed between the PBXs to exercise and test basic calls as well as QSIG supplementary services such as call transfer, call
conference, and call forward.
•Using the Siemens PBX configurations and Cisco IOS voice gateway configurations in this application note, successful toll bypass
integration was achieved. This includes basic call, call transfer, call conference, and call forward, with some limitations on Caller ID
features during transfer scenarios. These limitations are detailed in the following sections and all were found to be inherent to the
Siemens PBXs. Thus, H.323 toll bypass introduced no new restrictions to the available features or performance.

Features Not Supported
• Call Hold
• MWI
Limitations
•On basic calls, Connected Number was supported in lieu of Called (Alerting) Number. This is inherent to the PBXs and also occurs with
the PBXs connected directly via an E1 QSIG trunk.
•On Supervised Transfers, the original Calling Name and Number were displayed on the final destination phone only after the destination
answered and the transfer was completed. This is inherent to the PBXs and also occurs with the PBXs connected directly via an E1
QSIG trunk.
•On Supervised Transfers, the Called Name/Number were displayed on the originating phone only after the destination answered and the
transfer was completed. This is inherent to the PBXs and also occurs with the PBXs connected directly via an E1 QSIG trunk.
•Call Hold was not tested as a separate feature. The call is held automatically during Transfers or Conferences, and the call hold is
facilitated in NOTIFY message from Siemens HiPath/Hicom PBX. Aside from Transfers or Conferences, it is not possible to put a call
on hold from one of the Siemens HiPath/Hicom digital station phones. This is inherent to the PBXs and also occurs with the PBXs
connected directly via an E1 QSIG trunk.
•MWI was not tested, as a local voice mail system was not available on the PBXs at the time of testing.
