Hi,
I am looking for Link or document to help me understand what the benefits by centralizing our PSTN services. Current Environment:
Main and DR Site. Node at each for CM and Unity.
15 branch sites in and out of state on our Cisco VOIP system.
Each site uses it's own PSTN connection (POTS, PRI). Bigger sites have MTP resources setup locally. Others use main and DR site router.
I am looking at moving all PSTN inbound and outbound to a central SIP solution hosted at the main site.
Would the branch sites receive any network traffic relief if we consolidate all PSTN traffic to our main site?
Solved! Go to Solution.

Here is a good white paper from Cisco describing different PSTN deployment types:

Centralizing trunking will require more bandwidth at the remote sites as now calls that would normally go out of local gateways will traverse your WAN, the benefits are for example consolidation of trunking which typically leads to needing much less ports, ease of management, etc.
