Infrastructure
This section lists known interoperability issues with infrastructure components. These may manifest themselves as
issues with a particular endpoint or series of endpoints.
Equipment
Version
Results
Cisco TelePresence
Video Communication
Server (VCS)
X7.1
 When interworking between H.323 and SIP, the VCS
does not perform offer/answer correctly for G.729
codecs.
This can manifest itself as a lack of audio on
interworked calls that use G.729 codecs. (CSCty97265)
 An endpoint may end up in a half encrypted call
where the call leg from EP > CUCM > VCS is
unencrypted and the call leg from VCS > MCU
is encrypted.
Cisco Unified
Communications
Manager (CUCM)
8.6(2a)
 No video received from Cius when Cius dials in via
CUCM and is interworked to H.323 by VCS.
(CSCty51760)
 In networks in which not all call legs are encrypted,
calls may drop after using hold and resume. When
using encryption it is recommended that all call legs are
encrypted. (CSCtr52491)
Cisco TelePresence
Content Server
S5.3
Tested H.323 and SIP.
No issues found. The MCU 5300 Series only supports Cisco
TelePresence Content Server running version S5.3 or later.
Cisco TelePresence
MCU 4200 Series
Cisco TelePresence
MCU 4500 Series
Cisco TelePresence
MCU MSE Series
4.3(1.68)
Tested H.323 cascading.
 Cascading is not supported between MCU 5300 and
other MCU platforms running 4.3(1.68) or earlier.
Cascading is supported when those MCUs are running
version 4.3(2.18) or later. (CSCtz03995)
Polycom MGC
9.0.4.3
Tested H.323.
 H.264 video between the MGC and the MCU is not
supported if the call bandwidth is 384kbps or less.
To avoid this, either use a higher bandwidth or disable
H.264 when dialling the MGC using custom codec
selection. (CSCts46389)
Tandberg Gatekeeper
N5.2
No issues found.
Polycom PathNav
7.00.03
