OneStream Programming Guide

SIP Server
Enter the fully qualified domain name or IP Address of the SIP Registrar, Proxy Server or SIP PBX
that the calls should be routed to.
SIP Port
Enter the SIP Port that is used by the SIP Proxy / PBX. The default SIP Port is 5060.
NAT Traversal
Select whether NAT (Network Address Translation) is required for this SIP Group. Normally, NAT is
only set to Enable when the OneStream is behind a Firewall and the Server / PBX is located
outside of the Firewall (for example when connecting with an Internet Telephone Service Provider).
Call Limit
Enter the maximum number of simultaneous SIP calls that are permitted. This can be useful to
maintain a high call quality. Set to 0 to allow unlimited calls.
From
(Optional) Overrides the setting of the SIP From field. This is required by some Service providers
and PBXs which require the From field to always be set to the registered user and domain (e.g.
[email protected]).
Registration Required
Place a tick in this checkbox if the SIP Registrar / Proxy / PBX requires that the OneStream register
and login.
Username
(Optional) Enter the Username required by the SIP Registrar / Proxy / PBX.
Auth Username
(Optional) Enter the Authorisation Username required to register to the SIP Registrar / PBX. This is
only required if it is different to the Username (if the “Auth Username” is left blank then the
“Username” will be used during registration).
Password
(Optional) Enter the Password required by the SIP Registrar / Proxy / PBX.
Contact
(Optional) Enter the contact extension that will be used by the SIP Registrar / Proxy / PBX to send
calls to OneStream. Leave this field blank to use the default contact extension of “s” (an s must be
entered in dialled numbers in the routing for calls from the remote SIP Proxy).
New Registration button
If multiple registrations are required to the SIP Server / PBX then the New Registration button can
be clicked to add additional registration entries. Fill in as many Username/Password/Contact entries
as required.
