4.4.4. Launching calls
Once the preliminary settings are done, the procedure for a call on a codec (Codec 1 or Codec 2,
depending on the situation) is straightforward: dial a destination “number” and launch the call.
First of all, hit the
shortcut key and you reach the “Connection” page. Refer to the above chapter
describing this page and its elements (4.3.9, “Connection” page).
Preliminary note about the “number”
What we call here for simplicity a “number” is more generally a destination identifier. Its type depends
on the transmission network and, for audio over IP, on the protocol used. The possible types are:
Classical
phone number
: this is used for an ISDN destination, or a mobile voice call. A leading
“+” sign is used if the international prefix in included. If a sub-address if necessary, append a “*”
sign and the sub-address number.
Example “+33141361268*12”
IP address
: for an AoIP connection (SIP protocol or Direct RTP). The address is in the classical
“dot-decimal” format. If a port number must be specified, append ”:” and the port number.
Example: “192.168.24.65:5080”
For the SIP protocol, the port number to specify is the SIP port, if it differs from the default (“SIP
/ SIP Port” in the AoIP parameters). For “Direct RTP”, it is the RTP port, if different from the
default (“Direct RTP / RTP port3 in the AoIP parameters).
SIP URI
(Uniform Resource Identifier): this is an identifier with a general format
username@domain_name
, using alphanumeric characters.
Example: [email protected]
Actually
username
most often only includes numbers, for easier dialling on VoIP terminals. In
addition, the
@domain_name
part may be omitted if the caller is registered on the same server
(as the called unit).
In the end, a SIP number may be purely numeric, and very similar to a telephone number.
Direct dialing
In case of a SIP call, remember that in most cases the unit must be registered on a SIP server! Check
the SIP bar in the status panel on top of the screen.
On the area of the codec you want to call with, touch the “Dial” button
: the dial keypad pops up.
Enter/edit here the desired number, and touch the “OK” button.
You can see now the number set inside the “Connection pad”, ready for subsequent calls.
Touch the connection pad: the outgoing call is started towards the number. The pad changes colour to
show the various phases, and ends up green when the connection is established with the remote device.
A text line above the pad provides an explicit status as well. Chapter 4.5.2, “Connection pads” describes
the detailed behaviour of this element.
