IP 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 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:
To activate registration, you also need to set the parameter
'Registration Mode' to 'Per Account' in the Hunt Group Settings
table for the specific Hunt Group.
The Hunt Group account registration is not affected by the
parameter IsRegisterNeeded.
Contact User
[Account_ContactUser]
Defines the AOR user name. This appears in REGISTER From/To
headers as ContactUser@HostName, and in INVITE/200 OK
Contact headers as ContactUser@<device's IP address>.
Notes:
If this parameter is not configured, the 'Contact User' parameter
in the IP Group table is used instead.
If registration fails, then the user part in the INVITE Contact
header contains the source party number.
Application Type
[Account_ApplicationType]
Defines the application type:
[0] GW/IP2IP = (Default) Gateway application.
