Table 5-8: General Parameters (Protocol Definition)
Parameter Description
Enable GRUU
[EnableGRUU]
Determines whether or not the Globally Routable User Agent
URIs (GRUU) mechanism is used.
Valid options include:
[0] Disable = Disable (default)
[1] Enable = Enable
The gateway obtains a GRUU by generating a normal
REGISTER request. This request contains a Supported
header field with the value “gruu”. The gateway includes a
“+sip.instance” Contact header field parameter for each
contact for which the GRUU is desired. This Contact
parameter contains a globally unique ID that identifies the
gateway instance.
The global unique id is as follows:
If registration is per endpoint (AuthenticationMode=0), it is
the MAC address of the gateway concatenated with the
phone number of the endpoint.
If the registration is per gateway (AuthenticationMode=1) it
is only the MAC address.
When the “User Information” mechanism is used, the
globally unique ID is the MAC address concatenated with
the phone number of the endpoint (defined in the User-
Info file).
If the Registrar/Proxy supports GRUU, the REGISTER
responses contain the “gruu” parameter in each Contact
header field. The Registrar/Proxy provides the same GRUU
for the same AOR and instance-id in case of sending
REGISTER again after expiration of the registration.
The gateway places the GRUU in any header field which
contains a URI. It uses the GRUU in the following messages:
INVITE requests, 2xx responses to INVITE, SUBSCRIBE
requests, 2xx responses to SUBSCRIBE, NOTIFY requests,
REFER requests, and 2xx responses to REFER.
Note: If the GRUU contains the "opaque" URI parameter, the
gateway obtains the AOR for the user by stripping the
parameter. The resulting URI is the AOR.
For example:
AOR: sip:alice@example.com
GRUU: sip:alice@example.com;opaque="kjh29x97us97d"
User-Agent Information
[UserAgentDisplayInfo]
Defines the string that is used in the SIP request header
'User-Agent' and SIP response header 'Server'. If not
configured, the default string 'AudioCodes product-name s/w-
version' is used (e.g., User-Agent: Audiocodes-Sip-Gateway-
Mediant 2000/v.4.80.004.008). When configured, the string
'UserAgentDisplayInfo s/w-version' is used (e.g., User-Agent:
MyNewOEM/v.4.80.004.008). Note that the version number
can't be modified.
The maximum string length is 50 characters.
