SIP User's Manual 17. SIP Definitions
Parameter Description
Group’ table is used instead.
This parameter can be up to 49 characters.
Register
[Account_Register]
Enables registration.
 [0] No = Don't register
 [1] Yes = Enables registration
When enabled, the device sends REGISTER requests to the
Serving IP Group. In addition, to activate registration, you also
need to set the parameter 'Registration Mode' to 'Per Account' in
the Trunk Group Settings table for the specific Trunk Group. The
Host Name (i.e., host name in SIP From/To headers) and Contact
User (user in From/To and Contact headers) are taken from this
table upon a successful registration. See the example below:
REGISTER sip:xyz SIP/2.0
Via: SIP/2.0/UDP
10.33.37.78;branch=z9hG4bKac1397582418
From:
<sip:ContactUser@HostName>;tag=1c1397576231
To: <sip: ContactUser@HostName >
Call-ID: 1397568957261200022256@10.33.37.78
CSeq: 1 REGISTER
Contact:
<sip:ContactUser@10.33.37.78>;expires=3600
Expires: 3600
User-Agent: Sip-Gateway/v.6.00A.008.002
Content-Length: 0
Notes:
 The Trunk Group account registration is not affected by the
parameter IsRegisterNeeded.
 For the IP2IP application, you can configure this table so that a
specific IP Group can register to multiple ITSP’s. This is
performed by defining several rows in this table containing the
same Served IP Group, but with different Serving IP Groups,
user/password, Host Name and Contact User parameters.
 If registration to an IP Group(s) fails for all the accounts defined
in this table for a specific Trunk Group, and if this Trunk Group
includes all the channel
s in the Trunk Group, the Trunk Group is
set to Out-Of-Service if the parameter OOSOnRegistrationFail
is set to 1 (see 'Proxy & Registration Parameters' on page 228).
Contact User
[Account_ContactUser]
Defines the AOR user name. It appears in REGISTER From/To
headers as ContactUser@HostName, and in INVITE/200 OK
Contact headers as ContactUser@<device's IP address>. If not
configured, the 'Contact User' parameter in the IP Group Table
page is used instead.
Note: If registration fails, then the user part in the INVITE Contact
header contains the source party number.
Application Type
[Account_ApplicationType]
Note: This parameter is not applicable.
