Because the booklet of the 1st version, the CTI international has replaced considerably. the place it was interested in the combination of voice platforms with pcs, the focal point is now on IP-based voice, or converged networks and companies. this day, the telcos are upgrading their platforms from circuit-switched to IP-based packet-switched networks. businesses like Cisco platforms and Dow Chemical have put in IP-based telephones of their places of work around the world, saving thousands of greenbacks in provider charges. machine Telephony Integration, moment version has been up-to-date to mirror those contemporary adjustments within the and should support managers make the proper judgements for his or her communications infrastructure. It explains the enterprise and financial importance of the main built-in data-voice applied sciences and highlights the professionals and cons of every process. The textual content covers convergence, telephony criteria, new and robust instruments for name facilities, IP telephony(VoIP), infrastructure administration instruments, and complex enterprise functions. as well as the most recent advancements in ordinary CTI applied sciences similar to IVR, voicemail, speech popularity, and purposes, this version comprises increased chapters on safety, expense administration, name heart know-how, and IP telephony. Case stories offer a true global standpoint on the various latest CTI applied sciences. Bringing jointly the author's large event within the box, laptop Telephony Integration, moment variation may also help communications and IT pros make effective, reasonably priced judgements that would result in more desirable customer support, elevated productiveness, diminished expenditures, and more suitable workflow automation.

Example text

In common channel signaling (CCS), all the signaling information for one or more trunk groups is carried over a separate (not traffic bearing) channel. In a T1, for example, one of the channels would be for signaling and the remaining 23 would be available to carry traffic. Nonassociated CCS uses completely separate trunks or channels to provide signaling information. It is more economical and more flexible. Assume, for example, that a business has a promotion that causes lines to be swamped. With traditional CCS, available circuits may be swamped with call attempts, thus reducing the total capacity of the trunking available to an organization.

The number is dialed, then retained temporarily in memory. • The PBX (more often called communications server) syncs up the number dialed to the IP address of another PBX (the IP host). The link could be to a gateway if the called party is on the PSTN. • The calling PBX and the called IP host set up a session to handle packets from each other. Two channels are required for duplex (both directions) communications. • Packets between both parties are exchanged and converted into sounds via a CODEC.

For help desks, hunt-group configuration should be carefully designed. For example, assume that agents #1, #2, and #3 receive all calls in a hunt group. If the PBX always goes to agent #1 first, then the call workload will be skewed — #1 will never get a break and #3 may be underutilized. Random starts would be preferable in that work environment. Hunt groups and ACDs share many similar attributes. , always random or always go to agent #1 first). ACDs, on the other hand, can use more sophisticated CTI functions and capabilities within the switch itself to route a call.
