Certain carriers require that the Numbering Plan and Type of Number, sent in the ISDN SETUP message, be National/isdn-telephony (ISDN\Telephony e.163,4). Unless configured otherwise, the SmartNode will send this as UNKNOWN/UNKNOWN.
SETUP (DSS1 User)
To change this behaviour, you will need to configure the following mapping tables in your configuration. This configuation works for both SmartWare and Trinity VoIP devices.
routing-table called-e164 RT_FROM_SIP mapping-table calling-type-of-number to calling-type-of-number MAP_TO_NATIONAL mapping-table calling-numbering-plan to calling-numbering-plan NATIONAL complex-function ISDN_NATIONAL
Once you have implemented these config changes, you will simply have to route your SIP interface to the routing-table RT_FROM_SIP, as seen below.
interface sip IF_SIP
The SETUP message will now look like this.
