Sip Access - Aastra Ascotel IntelliGate A150 System Manual

2. 1. 3

SIP access

The PBX can be connected to one or more SIP providers via the Ethernet interface
on the basic system. The PBX supports 10 SIP access with up to 30 channels per SIP
access. One SIP Access Channels
The PBX handles the SIP access in the same way as analogue or digital network in-
terfaces, i. e. they are grouped in one or more separate trunk groups. Allocation to
an SIP provider is defined for each trunk group. This means that international calls
can be routed via SIP providers in different countries for example.
The PBX 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 network, for ex-
ample 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 regis-
trar and an SIP identification number (SIP-ID). The SIP-ID is linked with a direct 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 Ascotel® IntelliGate® to one or more SIP providers, sev-
eral Ascotel® IntelliGate® systems can also be networked via SIP.
