Figure 8-47: Manipulating Invite Destination Number - AudioCodes MediaPack MP-124 User Manual

SIP User's Manual
For example, in SAS emergency state, assume an incoming INVITE has a destination
number "7001234" which is destined to a user whose registered in the SAS database as
"552155551234". In this scenario, the received destination number needs to be
manipulated to the number "552155551234". The outgoing INVITE sent by the device then
also contains this number in the Request-URI user part.
In normal state, the numbers are not manipulated. In this state, SAS searches the number
552155551234 in its database and if found, it sends the INVITE containing this number to
the UA.
To manipulate destination number in SAS emergency state:
1. Load an ini file to the device with the following setting to enable inbound manipulation:
SASInboundManipulationMode = 1
2. Open the 'SAS Configuration' page (Configuration tab > VoIP menu > SAS > Stand
Alone Survivability).
3. Click the IP to IP Inbound Manipulation Table
Inbound Manipulation' page.
4. Enter a table index number, and then click Add.
5. Define the rules as required, and then click Apply.
The figure below displays a manipulation rule for the example scenario described above
whereby the destination number "7001234" is changed to "552155551234":
In the figure above, the following configuration is done:
Manipulated URI field: 'Destination'
Destination Username Prefix field: '700xxxx'
Request Type field: 'INVITE'
Remove From Left field: '3'
Prefix to Add field: '55215555'
