Abstract

The objective of this thesis work is design a pilot project of IP telephony based on Asterisk and integrates to Cisco Unified Communications Manager "CUCM" of the Salesian Polytechnic University Quito for the scalability of new extensions. Were performed the configurations of a central telephone based in Asterisk to make and receive calls, for internal communications that is with users of the UPS CUCM of different campus and external communications to the PSTN, some advanced services were configured as: call transfer, call parking, voicemail, call queues, call pickup, conferences. This was done using SIP as the signaling protocol for all devices that connect to the Asterisk server, and is the protocol used for the trunk between Asterisk and the UPSQ CUCM. The results obtained in this project on the technical aspect were acceptable calls test made were successful and had no problems, in economic terms the estimated costs for implementing Asterisk in the UPSQ represent a very significant saving for the university. So this pilot project demonstrated that the integration of PBX based in Asterisk with the UPSQ CUCM is entirely feasible.
