Note:
If the technical log-on is not successful due to an in-
correct user name or incorrect password, the SIP subscriber
cannot establish any connections – no emergency calls ei-
ther.
When a SIP subscriber logs off, when terminating the program, for example, the
associated license will become available immediately. A license is also made
available when a SIP subscriber’s regular status query is not conducted. The
internal clock for automatic log-out is determined by the
Profile
assigned under
Telephony: Devices: VoIP Phones
. The (
Keepalive
) internal clock setting is
located on the
Telephony: Extended: VoIP Profile
page.
Detailed information on the current license assignment and on logged-on SIP sub-
scribers is located on the
System Info
:
Telephony
:
SIP phones
page. This page is
where you can reset license assignment at any time by clicking on
Reset licences
.
Technical Notes
The names of settings for the various SIP telephones or SIP programs are not
uniform unfortunately. Please refer to the
(Help)
on the
Telephony: Devices: VoIP
Phones
page and the following notes when configuring SIP subscribers:
■
The “REGISTER” SIP message must be sent to the IP address of the Aastra 800
using the 5060 destination port. For SIP subscribers, this setting is frequently
located under “SIP Server” or “SIP Settings” with the terms “Domain”, “Server
IP” and “Server Port”.
■
The “REGISTER” SIP message must contain a valid user name and the appro-
priate password (the
User name
and
Password
fields in the
Configurator
under
User Manager: User
). For SIP subscribers, this setting is frequently
located under “SIP User Settings” or “SIP Account” with the terms “Authori-
zation User” and “Password”.
■
The “REGISTER” SIP message also contains a SIP-URI in the spelling for e-mail
addresses, for example
"Displayname" <sip:[email protected]>
.
The text portion of the SIP-URI (“Display Name”) is not evaluated at log-on from
the Aastra 800. The series of characters before “@” is the “User Name” or “SIP
Username”. The internal call number of the user must always be used here (the
Ph.No.
field in the
Configurator
under
User Manager: User
). The series of
characters after “@” is the “Domain Name” or the “SIP Domain”. The IP address
of the Aastra 800 must always be used here.
