[cisco-voip] So is the Lifesize H.320 gateway actually a 3545?

[Robert Kulagowski]

Or is the 3545 a Lifesize Gateway?  The features seem to be 
word-for-word, with the exception that someone did a global search and 
replace and either inserted/removed Lifesize or Cisco as necessary. 
Look at "Downspeeding" as an example...

Here's what the 3545 feature details have: 
http://www.cisco.com/en/US/docs/video/cuvc/release_5_1/gateway/3545/installation/guide/all_gw_functionality.html
Dual video
The gateway supports H.239 standards-based dual video and TANDBERG 
DuoVideo technology. Dual video streams enable a screen to carry video 
images from one source while simultaneously displaying images from a 
second source.

Hot swap
The gateway features hot swap functionality that you can use to remove 
and replace gateway cards under power.

Conceal caller ID
The gateway supports a conceal caller ID feature that instructs the 
gatekeeper to conceal the identity of the calling endpoint on the IP or 
ISDN network, whether the presentation restricted feature is enabled or not.

H.323 fast start
The gateway H.323 fast start feature enables endpoints to join a voice 
conference in the gateway more quickly.

ISDN rollover (available in Cisco Unified Videoconferencing 3545 PRI 
Gateway only)
The gateway features ISDN rollover. In this feature, the gateway sends a 
"busy out" channel request to the PSTN switch when the current PRI 
connection is left with less than a predefined number of available B 
channels. The PSTN switch "rolls over" to the next available gateway.

Network Specific Facility (available in Cisco Unified Videoconferencing 
3545 PRI Gateway only)
The gateway provides support for Network Specific Facility Information 
Elements (NSF IEs) which enable system administrators to specify to 
service providers the equipment, service, or network through which they 
want a call routed.

ISDN connection failure
The gateway responds to ISDN connection failure events, by unregistering 
from its gatekeeper. The gatekeeper is forced to send new IP-to-ISDN 
calls through a different gateway, thus ensuring high call completion 
rates. The gateway re-registers to the gatekeeper when the ISDN 
connection is restored.

Downspeeding
The gateway features downspeeding functionality. In the downspeeding 
feature, the gateway attempts to reconnect a disconnected video call 
either at a lower bandwidth or as a voice call. Downspeeding contributes 
to a higher percentage of call completion on the network. The gateway 
supports downspeeding at call setup and in mid-call.

Multiple trap server support
The gateway supports up to three SNMP trap servers.

Here's the Lifesize gateway features:
