Use multiple SIP accounts

I have tested with the Voicent SDk provided in c# for a simple call interface.Can you please help me how to use multiple SIP accounts for calling list of numbers at a time using SDK.

Actually, you do not have to do anything special from the C# interface. The gateway has a built-in scheduler and will automatically choose an available line for outbound calls. If you submit more call requests to the gateway, it will queue the calls.

To set up multiple SIP account, open gateway main window, select Setup > Options > SIP tab, click the Add button to add SIP account. You can add as many account as you wish. The total number of lines that can be started is determined by the lines you purchased. For shareware, you can start up to 10 lines.
