3.6 SIP Server

Introduction of SIP Server:
1）SIP server is the main component of VoIP network and is responsible for establishing all the SIP calls.
SIP server is also called SIP proxy server or register server. Both IPPBX and softswitch can act as the role of
SIP server.
2）Usually, SIP server does not participate in media processing. Under SIP network, media always use
end-to-end negotiating. Simple SIP server is only responsible for the establishment, maintenance and
cleaning of sessions, while relatively-complex SIP server (SIP PBX) not only provides basic calling and
conversational support, but also offers rich services such as Presence, Find-me and Music On Hold.
3）SIP server based on Linux platform like OpenSER, sipXecx, VoS, Mera or other.
4）SIP server based on Windows platform like mini SipServer, Brekeke, VoIPswitch or other.
5）Carrier-grade softswitch platform like Cisco, Huawei, ZTE or other.
