Introduction
SIP (Session Initiation Protocol) is used for Voice over IP. It is defined by the
IETF (Internet Engineering Task Force) in RFC2543 and RFC3261. SIP
trunking is the term used for linking a PBX, such as the NEC SL1100 system,
to the public telephone network by means of VoIP. This provides the ability for
users to place and receive communications and services from any location
and for networks to identify the users wherever they are located.
SIP analyzes requests from clients and retrieves responses from servers then
sets call parameters at either end of the communication, handles call transfer
and terminates.
The NEC SL1100 system implementation and programming for SIP are very
similar. The call routing, call features and speech handling (RTP) are the
same. Only the signaling protocol is different.
With the NEC SL1100 system, SIP trunks can receive incoming calls with
Caller ID, place outgoing calls, and transfer SIP trunks to IP, SIP, analog and
digital stations, and across a network.
Currently, however, SIP Centrex Transfer and E.164 Numbering Plan are
not supported.
If a common carrier supports SIP, the NEC SL1100 can connect the SIP
Carrier and outgoing calls to the PSTN (Public Switched Telephone Network)
network and the common IP network using an NEC SL1100 SIP trunk.
