This type of installation allows dynamic IP addresses. Each piece of equipment (including
ALERT) registers at startup with the current registar sip. The latter is often the proxy.
The operation is the same as with the proxy alone... The difference is that the IP / phone
numbers correspondence is done dynamically.
In this mode, the PBX is in charge of the Caller Name Identification. It won’t be possible to
send text messages via CNI.
In this particular case, you need to specify the data identification supplied by the telephony
In our case, ALERT registers itself with its login and password for the call number 1001
The user record setup is the same as the setup with proxy.
The call addresses are of type: sip:email@example.com or simply 1010.
With a subscription to a SIP provider.
The configuration of the driver then depends on data supplied by the provider.
With Asterisk or another IPBX. This time it is the administrator of the telephone system that
provides the data to specify in ALERT.
The driver can't be initialized (code 1):
The IP port configured in the SIP driver is already used by another program. Change its value
in the Connection tab.
The phone rings, but no sound is played when picked-up:
Check the network card used by Alert. In the Connection tab select the correct IP address
(network card). This address must have access to the telephony network.
File XX can't be played (code 4):
The audio file format is not supported by Alert. Check the audio file format. It must be PCM
(no compression) mono in 8 or 16 bits.
