 The SIP TAPI is a TAPI driver, which enables SIP click2dial functionality from TAPI applications (like MS Outlook, Phoner ...). The correct term for this application is: A service provider for the MS telephony API.

 

The work is based on asttapi, a TAPI driver which connects to Asterisk via the manager interface (a telnet connection into Asterisk). I removed all the asterisk/telnet related stuff and replaced it with a SIP stack (eXosip2). Thus, it should work with all SIP based applications (which understand the REFER reqeust).

 

How does it work?

 

The SIP TAPI sends an INVITE request to your own SIP phone. When you pick up the phone and the call between the SIP TAPI and your phone is established, the SIP TAPI sends a REFER request to your phone. This REFER request contains the originally called phone number in the Refer-To: header. Thus, your SIP phone will establish a new call to respective phone number. For a detailed howto please refer to the SIPTAPI-Tutorial.

 

The SIP TAPI is tested with Windows XP SP2 german, Outlook 2003 SP1, MS Visual Studio.NET 7.1, Phoner.de 
 
 

Install it:

 

1. unzip it and copy the siptapi.tsp file into \windows\system32\

 

2. Install the TAPI driver via the control panel: Start -> ControlPanel -> PhoneAndModemOptions -> Advanced -> Add -> SIP TAPI Service Provider

 

Configuration:

1. Configure via the control panel: Start -> ControlPanel -> PhoneAndModemOptions -> Advanced -> Configure

 - SIP domain: mydomain.com (replace mydomain.com with your domain)

 - Outbound Proxy: pbx.mydomain.com;lr (replace mydomain.com with your domain)

 - username: 200 (replace with your extension number)

 - password: 200 (replace with your password)

 

2. Configure your TAPI application to use the SIP TAPI
