QUESTION: 1
A customer has a network that contains several Communication Server (CS) 1000 Rls 4.0
systems. They are networked together via Virtual Trunks. The customer has limited bandwidth on
the WAN links between sites and has an Optimized WAN link to carry Voice calls that use
G.729A. Which configuration setup will ensure that G.729 is always used on a virtual trunk call
between sites?
A. No extra configuration is needed. Virtual Trunk calls always use G.729A CODEC.
B. ? configure the virtual route to be in same zone as voice gateway channels and IP sets ? verify
that the customer has G.729A as part of CODEC profile ? verify all zones at the site are configured
with best quality for intrazone calls and best bandwidth for interzone calls
C. ? virtual route is configured to be in different zone than the voice gateway channels and IP sets
? verify the customer has G.729A as part of CODEC profile ? ensure all zones at the site are
configured with best quality for intrazone calls and best quality for interzone calls
D. ? the virtual route is configured to be in a different zone than voice gateway channels and IP
Sets for each system ? verify the customer has G.729A as part of CODEC profile ? ensure all zones
at the site are configured with best quality for intrazone calls and best bandwidth for interzone
calls
