Call Proceeding IW Procedure

Disabled (Default) - When set to Disabled, the ISDN Call Proceeding to SIP 183 Progress Interworking functionality is disabled. The IMG will NOT interwork the Progress Indicator parameter no matter what its values is.

Enabled - When set to Enabled, the ISDN Call Proceeding to SIP 183 Progress functionality is enabled on the ISDN side. The ISDN Progress Indicator will be interworked into the SIP 183 Progress message if the Progress Indicator value is either No. 1 or No. 8. After enabling the ISDN side, the SIP side must also be configured. This is accomplished under the SIP_ISDN Interworking object. For configuration information on the feature, refer to the Map ISDN Call Proceeding to SIP 183 topic.
