ip pbx and cisco unified comunication

Recommended Posts

Well revan,

 

the difference is actually between the PBX as a term and the CUCM as a software based PBX or what is called (Softswitch). in the recent days IP PBX, softswitch, CUCM Server are all used interchangeably; going back to history a PBX is a Private branch exchange which is somewhat a smaller central office form, PBXs are using the circuit switched networks its means that they use a cards to support the different Analog or digital extensions and each port on the card is used to connect one telephone directly to the PBX and these would require a separate infrastructure than your data infrastructure. Avaya and Nortel were the leaders on manufacturing the PBXs since 1900s when they were one company called AT&T. When technology evolved and packet switched networks start to evolve (IP). Traditional PBX starts to evolve to support the IP Extension by integrating a signaling server in their solutions to support IP Extensions hence the word IP PBXs, or IP enabled PBXs or hybrid PBX came which support IP in addition to Analog and Digital through cards.

On the other hand the newest companies to the field starts to deploy a fully software based solutions which will be installed on sever to support IP Telephony hence came the word softswitch (ex. Cisco and Microsoft).

These softswitchs are not capable of integrating directly to traditional telephones or PTSN unless the is a form of circuit switched card (DSPs0) that are regularly hosted in a router called gateway.

Hope this was helpful
