Objective

To send digits as the called party's extension number in a connected Video SIP call. 

Applies To

• SIP Interconnect
• Video API
• DTMF Digits

Procedure

1. Initiate the SIP call by a dial-out to the destination number. 
2. Once the SIP call is connected, send DTMFs with the pauses if needed to delay sending the DTMFs. Pausing the DTMF delivery is useful in dialing a destination extension number through an IVR selection. For example, dial extension 1000 with a pause as pp1000 where p=500ms. Before the DTMF 1000 gets sent, it waits for a second before sending the digits 1, 0, 0, 0.
