Parameter Description
configure voip > sip-definition
settings > force-generate-to-tag
[ForceGenerateToTag]
Enables the device to generate the 'tag'
parameter's value in the SIP To header.
This is applied to the first SIP response,
received from the called party, which the
device sends to the dialog-initiating SIP
user agent (caller). In other words, this
device-generated To tag overwrites the
original To tag generated by the called
party. All SIP messages between the
device and caller use this generated To tag,
while all SIP messages between the device
and called party use the To tag generated
by the called party. As the device-generated
To tag value is short (up to 12 characters),
this feature may be useful for SIP UAs that
cannot handle long tag values.
An example of the To tag:
To: Alice@company.com; tag =
9777484849@10.10.1.110
â– [0] = Disable (default). The device
forwards the To tag transparently
between the SIP UAs.
â– [1] = Enable. The device generates the
To tag in the response sent to the
initiator of the SIP dialog.
Note: The feature is applicable only if the
'SBC Operation Mode' parameter is
configured to B2BUA. This can be
configured in the SRD and IP Groups table.
However:
â– The IP Group's 'SBC Operation Mode'
parameter takes precedence over the
SRD's 'SBC Operation Mode'
parameter. For example, if the IP Group
is configured for B2BUA but its'
associated SRD is not, then the tag-
generation feature can function.
â– If the IP Group's 'SBC Operation Mode'
parameter is not configured (-1), the tag-
generation feature for the IP Group is
functional only if its' associated SRD is
configured for B2BUA.
â– For call routing between IP Groups, the
feature can only function if both IP
Groups are configured for B2BUA, or if
one or both of them is not configured (-
1), but the associated SRD is
configured for B2BUA.
