How to call SIP line

I have downloaded the latest Voicent gateway and installed it successfully on Windows XP machine. I have used SIP based setup for the Voice gateway and the gateway is started successfully. I have installed the timeofday application in the gateway. But i’m unable makeout how to launch the timeofday application from the SIP smartphone (Which number to dial), please help me in solving this issue

When Voicent is started with SIP, it registers each line as a SIP softphone. The soft phone is registered with your SIP service provider using the SIP ID you specified in the gateway. It usually takes the form as: sip:your_account@your_provider.com.

From your SIP smartphone, or any SIP soft phone (like x-lite), you can call the gateway using the SIP ID. The gateway should then answer the call and use the timeofday application for the interaction.

In many cases, especially deployed for commercial use, a DID (direct inbound dialing) number, which is a regular phone number, is purchased for your SIP ID. Once you have a DID number, people using ordinary phone (landline or cell phone) to call that number, and the call will be forwarded to the SIP line.
