User's Manual 434 Document #: LTRT-27055
Mediant 1000B Gateway & E-SBC
Parameter Description
If the IP Profile name contains one or more spaces, you must
enclose the name in double quotation marks, for example:
X-AC-Action: 'switch-profile;profile-name="My IP Profile"'
The Message Manipulation rule adds the proprietary header with the
value of the new IP Profile to the incoming re-INVITE or UPDATE
message and as a result, the device uses the new IP Profile for the
SIP entity and stops sending it SIP INFO messages. You can also
configure an additional Message Manipulation rule to re-start the
sending of the SIP INFO. For example, you can configure two
Message Manipulation rules where the sending of both SIP INFO
and RFC 2833 depends on the negotiated media port -- the device
stops sending SIP INFO if the SDP of the re-INVITE or UPDATE
message contains port 7550 and re-starts sending if the port is 8660.
The rule that re-starts the SIP INFO switches the IP Profile back to
the initial IP Profile that enables the sending of DTMF digits using
both methods (i.e., 'Send Multiple DTMF Methods' is configured to
Enable). The configured Message Manipulation rules for this
example are shown below:
Index 1
Message Type: reinvite.request
Condition: body.sdp regex (.*)(m=audio 7550 RTP/AVP)(.*)
Action Subject: header.X-AC-Action
Action Type: Add
Action Value: 'switch-profile;profile-name=ITSP-Profile-2'
Index 2
Message Type: reinvite.request
Condition: body.sdp regex (.*)(m=audio 8660 RTP/AVP)(.*)
Action Subject: header.X-AC-Action
Action Type: Add
Action Value: 'switch-profile;profile-name=ITSP-Profile-1'
The Message Manipulation rules must be assigned to the SIP
entity's IP Group, using the 'Inbound Message Manipulation Set'
parameter.
Note:
To send DTMF digits using both methods (i.e., when the
parameter is enabled), you need to also configure the following:
Configure the 'Alternative DTMF Method'
(IPProfile_SBCAlternativeDTMFMethod) parameter to one of
the SIP INFO options (INFO – Cisco, INFO – Nortel, or
INFO – Lucent).
Enable the sending of DTMF digits using the RFC 2833
method, by configuring the 'RFC 2833 Mode'
(IpProfile_SBCRFC2833Behavior) parameter to As Is or
Extend.
When using the X-AC-Action header to switch IP Profiles, it is
recommended that the settings of the switched IP Profile are
identical (except for the 'Send Multiple DTMF Methods'
parameter) to the initial IP Profile in order to avoid any possible
call handling errors.
This feature requires DSP resources (for detection and
generation of RFC 2833).
The parameter is applicable only to the SBC application.
