UNREGISTERED MODE
Placing a call in Unregistered EBU3326/SIP mode is simple: just build a custom Audio Pro fi le in the Pro fi le Manager
Tab , but instead of choosing BRIC Normal as the Channel, choose EBU3326/SIP . This will make sure the call is
ini ated on the proper ports and with the proper signalling. The majority of system se ngs rela ng to EBU3326/
SIP relate to
Registered mode.
REGISTERED MODE
Registering with a SIP server in EBU3326/SIP mode can have some advantages. When using a SIP server:
• The server can be used to help make connec ons between codecs through routers.
• The remote codec can be dialed by its SIP URI instead of IP address.
• The SIP server can be used to
fi nd codecs on dynamic IP addresses.
SIP SERVERS
A SIP server exists in a domain. This domain is represented by a web-style URL like sipphone.com or iptel.org . A SIP
server or proxy generally handles IP connec ons within its domain.
SIP URI
A URI is an address method used for establishing connec ons via a SIP server, similar to a URL for websites. The SIP
server assigns a
fi xed alphanumeric name to each subscribed account. For example, an Iptel user may be assigned
the user name comrex_user. URIs consist of a SIP user name, followed by a domain, delineated with the @ symbol,
like an email address. Comrex’s Iptel user URI would be comrex_user@iptel.org. Comrex devices do not use the
designa on “sip:” before a SIP address.
If a connec on is made exclusively within a single domain, the domain name can be le o ff . As an example, to make
a call to this codec from another Iptel registered codec, the dialing string can simply be comrex_user (with the
domain being assumed).
REGISTERING WITH A SERVER
At a minimum, you will need the following informa on when registering BRIC-Link II with a SIP server:
• The Internet address of your SIP proxy/server (e.g. proxy01.sipphone.com );
• The username on the SIP account (this is usually the dialing address);
• The password on the SIP account.
Figure 75 shows how this informa on can be applied: by enabling the Use SIP Proxy op on under EBU 3326/SIP
on the Systems Se ngs Tab . Add the necessary creden als listed above for the SIP domain login, and click “Apply
Changes” to save each se ng.
