Cisco IP Communications Voice/Fax Network Module (part numbers NM-HD-1V, NM-HD-
2V, or NM-HD-2VE) on Cisco IP Communications High-Density Digital Voice/Fax Network
Module (part numbers NM-HDV2, NM-HDV2-1T1/E1, or NM-HDV2-2T1/E1 and associated
DSP cards PVDM2-8, PVDM2-16, PVDM2-32, PVDM2-48, and PVDM2-64)
More information about transcoding is available at
http://www.cisco.com/en/US/products/ps5854/products_qanda_item0900aecd8016c2c7.shtml.
Note: The Cisco 7200 Series Routers and the Cisco 7301 Router do not support transcoding.
The Cisco IOS Software images listed in Table 2 allow the simultaneous operation of the Cisco
Unified Border Element, the Cisco IOS Software H.323 Gatekeeper, and the Cisco TDM Gateway,
all on the same device.
Cisco Unified Border Element with Configurable SIP Profiles
Configurable SIP Profiles on the Cisco Unified Border Element help customers by allowing SIP
messages from entities in their network to pass through the border element and have header fields
and the embedded SDP manipulated. This configurability allows for more endpoints to
interconnect by acting as a middle layer to provide some interpretation. For example, if one
network requires that a certain header be present in a SIP message, but your current SIP device,
such as Cisco Unified CallManager, does not generate the header, the SIP profiles capability can
be used to add this header.
Summary
The Cisco Unified Border Element provides direct IP interconnections with lower cost and greater
flexibility than TDM interconnections. This gateway helps service providers and enterprises
decrease VoIP latency, improve voice quality, and effectively support rich-media services, thereby
allowing Cisco Unified Communications products to work transparently in both intrasite and
intersite deployments.
