SIP User's Manual 3. Web-Based Management

Parameter Description

parameter isn't included. If a 'tgrp' value is specified in incoming

messages, it is ignored.

 [2] Send and Receive = The functionality of outgoing SIP messages

is identical to the functionality described in option (1). In addition, for

incoming SIP messages, if the Request-URI includes a 'tgrp'

parameter, the device routes the call according to that value (if

possible). If the Contact header includes a 'tgrp' parameter, it is

copied to the corresponding outgoing messages in that dialog.

Enable GRUU

[EnableGRUU]

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:[email protected]

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-MediaPack/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.
