Determines whether the Globally Routable User Agent URIs (GRUU)
mechanism is used.
[0] Disable = Disable (default)
[1] Enable = Enable
The device obtains a GRUU by generating a normal REGISTER request.
This request contains a Supported header with the value 'gruu'. The device
includes a '+sip.instance' Contact header parameter for each contact for
which the GRUU is desired. This Contact parameter contains a globally
unique ID that identifies the device instance.
The global unique ID is as follows:
If registration is per endpoint (AuthenticationMode=0), it is the MAC
address of the device concatenated with the phone number of the
endpoint.
If the registration is per device (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 device 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 device
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"
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 1000/v.5.40.010.006). When
configured, the string 'UserAgentDisplayInfo s/w-version' is used (e.g.,
User-Agent: MyNewOEM/v.5.40.010.006). Note that the version number
can't be modified.
The maximum string length is 50 characters.
Determines the value of the Owner line ('o' field) in outgoing SDP
messages.
The valid range is a string of up to 39 characters. The default value is
'AudiocodesGW'.
For example: o=AudiocodesGW 1145023829 1145023705 IN IP4
