SIP DTMF Support

Description:

SIP DTMF support object is created under the SIP SGP Profile object. The SIP DTMF Support object is used to enable and configure DTMF support in the Notify message of the Subscribe/Notify feature when sending a DTMF digit to another gateway. The supported DTMF digits are shown in the table below. Use this pane to enable and configure SIP DTMF support to send a DTMF digit to another gateway. There are two methods supported:

 

SIP INFO Method

SIP Subscribe/Notify

 

Note: When creating the SIP SGP profile the default ID which is ID:0 will not allow you to change any parameters. When creating the SIP SGP Profile and a custom profile will need to be configured change the ID to something other than ID:0. If the ID is 0 then the fields under the SIP SGP profile and any objects created underneath this object will be set to defaults and the fields in the subsequent objects can not be changed.
