8. Basic applications
The SIP Ring Switch has several communication paths and supports some standard
protocols. We recommend that you only enable the communication paths that are
actually required in your application. In this way, you limit the possibility of unwan-
ted third-party access and manipulation.
First of all, we would like to present the three most commonly used communication
paths:
SIP - Dialing via IP telephony
Registration in the telephone system
The basic prerequisite for using the SIP ring switch is connection to an IP PBX. For
this purpose, SIP access must first be activated under Communication channels >>
SIP. To register in the system, the following access data must be configured in the
SIP basic settings area:
Telephone system IP (Host 1)
IP address of the telephone system
Alternative telephone system IP (Host 2)
Configuring the IP address of a second telephone system is optional and allows to
set up redundant systems.
PJSIP server port
If the telephone system uses the PJSIP protocol (chan_pjsip), the UDP port configu
-
red in the telephone system (default 5060) must be entered here.
SIP server port
If the PBX uses the SIP protocol (chan_sip), the UDP port configured in the PBX (de
-
fault 5160) must be entered here.
SIP lokaler Port
UDP port on which the SIP ring switch receives datagrams from the PBX.
