Deciding which DSP solution to implement is generally based on the size of
the deployment; for instance, smaller size companies may want to consider
deploying a software-based solution.The Cisco CallManager is able to handle 24
MTP sessions, while a separate Windows server can support 48 sessions. It’s recommended
to run this service on a separate server since performance will be
affected on the CallManager for call processing. For medium size organizations, a
hardware solution such as the Catalyst 4000 would be more feasible.
The larger enterprise should consider the Catalyst 6000 solution with the
8-port T1/E1 Voice and Service module.The Catalyst 6000 module is a highly
scalable solution.We will next discuss the limitations of each of these modules.
