Placing a call in Unregistered EBU 3326/SIP mode is simple: just build a prole, but instead of choosing
channel, choose . This will make sure the call is iniated on the proper ports and with the proper signaling.
The majority of system sengs relang to EBU 3326/SIP relate to mode.
Registering with a SIP server in mode can have some advantages. When using a SIP server:
• The server can be used to help make connecons 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 nd codecs on dynamic IP addresses.
A SIP server exists in a domain. This domain is represented by a web-style URL like or . A SIP
server or proxy generally handles IP connecons within its domain.
The SIP server assigns a 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. Our Iptel user’s URI would be comrex_user@iptel.org. Comrex devices do not use the
designaon “sip:” before a SIP address.
If a connecon is to be made exclusively within a domain, the domain name can be le o. 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).
At a minimum, you will need the following informaon when registering NX with a SIP server:
1 The Internet address of your SIP proxy/server (e.g. proxy01.sipphone.com);
2 The username on the SIP account (this is usually the dialing address);
3 The password on the SIP account.
Below shows where this informaon can be applied in the secon. You will also need to enable
the opon in that menu.
