Modifying ISDN-to-IP Calling Party Number

You can use the Dial Plan file to change the Calling Party Number value (source number) of the incoming ISDN call when sending to IP.

Use the following syntax in the Dial Plan file:

<ISDN Calling Party Number>,0,<new calling number>

■

<ISDN Calling Party Number>: Calling party number (or its prefix) received in the ISDN call SETUP message. The source number can also be a range, using the syntax [x-y] in the Dial Plan file. This number is used as the display name in the From header of the outgoing INVITE.

■

The second number must always be set to "0".

■

<new calling number>: String of up to 12 characters containing the mapped number that is used as the URI user part in the From and Contact headers of the outgoing INVITE.

Below shows an example of such a configuration in the Dial Plan file:

[ PLAN1 ]
; specific received number changed to 04343434181. 
0567811181,0,04343434181
; number range that changes to 04343434181. 
056788118[2-4],0,04343434181

If we take the first Dial Plan rule in the example (i.e., "0567811181,0,04343434181"), the received Calling Number Party of 0567811181 is changed to 04343434181 and sent to the IP with a SIP INVITE as follows:

Via: SIP/2.0/UDP 211.192.160.214:5060;branch=z9hG4bK3157667347
From: <sip:04343434181@kt.co.kr:5060>;tag=de0004b1
To: sip:01066557573@kt.co.kr:5060
Call-ID: 585e60ec@211.192.160.214
CSeq: 1 INVITE
Contact:<sip:04343434181@211.192.160.214:5060;transport=udp>

To modify ISDN Calling Party Number using Dial Plan File:

1.

Create a text-based Dial Plan file containing your configuration (see above for syntax).

2.

Convert the Dial Plan file to *.dat file format using the DConvert utility. This is done by clicking the DConvert's Process Dial Plan File button. For more information, refer to DConvert Utility User's Guide.

3.

Load the Dial Plan file in *.dat format to the device.

4.

Specify the Dial Plan (by index number) that you want to use, using the Tel2IPSourceNumberMappingDialPlanIndex ini file parameter.
