  • · Solution A: Use a central CallManager (perhaps redundant CallManagers) with each office being a separate region. Intra-region calls can be G.711, but inter-region calls can be G.729 (unless to voice mail). Limit WAN bandwidth at each egress point and block calls that will exceed that level. · Solution B: Put a CallManager in each location and network them together using H.323 (running on a Cisco IOS gatekeeper). You can then use the zone bandwidth feature to limit the number of calls and force overflow to the Pub lic Switched Telephone Network (PSTN)....

  • Internet telephony refers to communications services—voice, facsimile, and/or voice-messaging applications—that are transported via the Internet, rather than the public switched telephone network (PSTN). The basic steps involved in originating an Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet; the process is reversed at the receiving end.
