2. 1. 3. 5 SIP access
The communication server can be connected to one or more SIP providers via the
Ethernet interface on the basic system. The communication server supports 10 SIP ac-
cess with up to 30 channels per SIP access. One SIP Access Channels licence is re-
quired for each channel.
The communication server handles the SIP access in the same way as analogue or
digital network interfaces, i.e. they are grouped in one or more separate trunk groups.
The allocation to an SIP provider is defined for each trunk group. This means for exam-
ple that international calls can be routed via SIP providers in different countries.
The communication server must register with a registrar of the SIP provider so that the
SIP messages can be forwarded to the proxy server and from there to the public net-
work, for example via a gateway. At least one SIP account has to be set up for each
SIP provider. Each account contains a user name and password for identification with
the Registrar and an SIP identification number (SIP-ID). The SIP-ID is linked with a di-
rect dial number so that outgoing and incoming connections can be made. A total of
500 SIP accounts can be set up and linked with the corresponding direct dialling num-
bers.
One SIP account per SIP provider can be set up as a default account. It can then be
used by users without an SIP account for outgoing calls via a corresponding route or
for incoming calls via a special call routing.
Besides the connection of communication servers to one or more SIP providers, sev-
eral communication servers can also be networked via SIP.
System configuration
Set the SIP provider parameters using the configuration tool WebAdmin in the Call
routing ( =df) view:
• Under Network interfaces click the Add button to create a new SIP provider.
• Double-click the SIP provider you have just created to specify the settings for this
SIP provider. In this overlay view, create and also configure the SIP accounts.
Tips:
– Alternatively you can also configure the SIP provider by importing an SIP provider profile.
For this you must first export the settings of an already configured SIP provider into an XML
configuration file.
– In the Call routing ( =df)view you can access a context menu using your secondary
mouse key (right-clicking).
