Mapping Npi/Ton To Sip Phone-Context - AudioCodes Mediant 600 User Manual

User's Manual

"RN" - used in the rule to manipulate the Redirected number (i.e., originally called
number or Diverting number).

"DN" - used in the rule to manipulate the Diverted-to number (i.e., the new called
number or destination). This manipulation is done on the user part in the Contact
header of the SIP 302 response.
For example, assume the following required manipulation:

Manipulate Redirected number 6001 (originally called number) to 6005

Manipulate Diverted-to number 8002 (the new called number or destination) to 8005
The configuration in the Redirect Number Tel -> IP manipulation table is as follows:
Parameter
Destination Prefix
Redirect Prefix
Stripped Digits From Right
Suffix to Add
Number of Digits to Leave
After the above manipulation is done, the device sends the following outgoing SIP 302
response:

Mapping NPI/TON to SIP Phone-Context

The Phone-Context table page allows you to map Numbering Plan Indication (NPI) and
Type of Number (TON) to the SIP 'phone-context' parameter. The 'phone-context'
parameter appears in the standard SIP headers where a phone number is used (i.e.,
Request-URI, To, From, and Diversion). When a call is received from the ISDN/Tel side,
the NPI and TON are compared against the table and the matching 'phone-context' value is
used in the outgoing SIP INVITE message. The same mapping occurs when an INVITE
with a 'phone-context' parameter is received.
For example, for a Tel-to-IP call with NPI/TON set as E164 National (values 1/2), the
device sends the following SIP INVITE URI:
Version 6.6
