An IP Telephony solution encompasses several key components from voice capable LAN switches, call processing servers, IP endpoints, and unified communications applications.
IP Telephony starts with the network and a successful deployment of IP Telephony requires a well architected, stable network foundation utilising LAN switches capable of providing the appropriate Quality of Service (QOS) and Power over Ethernet (PoE).
IP Telephony components often include:
- PoE and QoS enabled LAN switches.
- Call Processing hardware and software.
- Voicemail and Unified Messaging hardware and software.
- IP Telephony endpoints e.g. handsets, softphones, video-enabled devices, and conferencing phones.
- Unified Communications applications e.g. collaboration tools, presence information, mixed media conferencing, data-sharing, and desktop integration.
