SIP / SIP-Q

Networks
In HiPath 3000/5000 V7 and later systems, networking is possible via:
SIP with HiPath 2000 / HiPath OpenOffice EE, HiPath 3000, HiPath 4000 and HiPath 5000
●
SIP-Q V2 with HiPath2000/HiPath OpenOffice EE, HiPath 3000, HiPath 4000, HiPath
●
5000 and OpenScape Voice
In HiPath 3000 V8 and HiPath 4000 V5 and later systems, only SIP-Q V2 protocol
>
is used for IP networking between these systems and only CorNet-NQ is used for
TDM networking. CorNet-IP protocol is no longer supported.
SIP
SIP (Session Initiation Protocol) is a network protocol for establishing, controlling and ending a
communication sessions between two or more stations. Actual payload is exchanged via other
protocols, such as SDP (Session Description Protocol) and RTP (Realtime Transport Protocol).
SIP-Q
SIP-Q V1 (SIP-QSig) is a network protocol enhanced by the QSig signaling protocol. QSig is
in turn enhanced by CorNet-NQ. In SIP-Q V1, QSig (incl. CorNet-NQ) is tunneled via SIP. This
enables more features to be implemented between the communication systems.
QSig is a signaling protocol based on ISDN for networking communication systems from differ-
ent manufacturers.
In addition to SIP-Q V1, SIP-Q V2 features the encryption protocol TLS (Transport Layer Se-
curity) for signaling and the transport protocol SRTP (Secure RTP) for encrypting payload. For
networking with HiPath 4000, the features SPE (Signaling and Payload Encryption) and DMC
(Direct Media Connection) are also supported. For each DMC call, one B channel is available.
