SIP AND HOSTED SIP

SIP is a voice over Internet Protocol (VoIP) technology based on the Session Initiation Protocol (SIP) by which Internet telephony service providers (ITSPs) deliver telephone services and unified communications to customers equipped with SIP-base Telephone Systems.

SIP works more like landline, in the sense a Trunk is effectively a Channel and you require a telephone system to host and deliver the calls to the handsets. SIP trunks also remove the need for physical lines from the exchange to the premises and they are cheaper than landlines.

Hosted SIP is a mixture between landline and Hosted VOIP by where the Trunks are hosted at a private data centre, and therefore it removes the need for physical on-site system and physical lines to the premises.

The handset would be programmed to connect wit the Host by way of IP addresses and gate-ways. It is fractionally more expensive than normal SIP however  it can save you the cost of maintaining/upgrading a telephone system.
