Description
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.
