Version 7.2 447 Mediant 800B Gateway & E-SBC
User's Manual 20. Coders and Profiles
Parameter Description
receives a SIP re-INVITE (or UPDATE) from the SIP entity to where
the SIP INFO is being sent (and keep sending the DTMF digits using
the RFC 2833 method). This is done using AudioCodes proprietary
SIP header X-AC-Action and a Message Manipulation rule (inbound)
to instruct the device to switch to a different IP Profile that is
configured to disable the sending of DTMF digits using both methods
(i.e., 'Send Multiple DTMF Methods' is configured to Disable):
X-AC-Action: 'switch-profile;profile-name=<IP Profile Name>'
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
