FAQ#1000

#### The TAPI application does not show any incoming calls (Action URLs).

> The Action URLs are not used in Asterisk driver. Here, the calls are detected via the Asterisk Manager Interface.

> Technical background:
> The TAPI driver set so called "Action URLs" in the phone. When a call event occours, an Action URL is triggered, an the phone establishes a TCP connection to the PC. The TAPI driver receives the event data from the phone and then generates a TAPI Call Event.

> Please check the following settings:

> Test preparation

> - Please install the current xtelsio program / driver version.

> - Restart the phone.
> - If necessary, restart your TAPI application.

> Test 1: Check phone IP address

> - Please make a test call with your TAPI application. If your phone starts dialing, the specified IP is correct. If the phone is not responding, please check in Configuration Dialog [Connection] if the IP address is valid for your phone.
>   If you enter the telephone IP address in your web browser, the web configuration from the phone should be visible.

> Test 2: Local IP Address

> - Check in Configuration dialog [Action URLs] if the correct local IP address is selected from your PC. To this IP address the phone sends the Action URL events. If necessary, click [Stop] to enable the selection box.
>   If there are several local IP addresses available and the phone is on the same network, select the IP from this network.
>   Important: Under the "Action URLs" you do NOT have to enter the IP of the phone, but that of your computer.

> Test 3: Local IP-Port

> - If a click on [Start] shows an error message, the port may be already in use. Then select a different port, for example 6000 or 8081.
> - If all tests were successful, but no Action URLs are received, try using another port, e.g. 4040 or 8081.

> Test 4: Firewall

> - Turn off your firewall for testing. Ask your administrator if another firewall is installed in addition to the Windows Firewall.
> - If the calls are displayed now, the firewall had blocked the Action URLs.
>   Solution: Click on "Configure Windows Firewall" button in Configuration dialog [Action URLs]. If another firewall is installed on your PC, turn in this port 8080 free for incoming TCP connections. You need admin rights for this action.
> - In Kontext der CTI Client Anwendung ist ggf. für die "cti_client.exe" auch der generelle Netzwerkzugriff in der Firewall freizugeben.

> Test 5: Test-Button

> - Click button "Open Test-URL in the browser" in the Configuration dialog [Action URLs]. If your web browser displays the text "<TAPI>Receive OK</TAPI>", the TAPI driver are able to receive Action URLs .
> - If your web browser is not displaying "<TAPI> Receive OK </TAPI>", you may select another port (eg 6000 or 8081). If your computer has multiple local IP addresses, check if you have the right selected.
> - Enter the Test-URL displayed in you browser (eg 192.168.0.100:8080) into a web browser on another PC. Here also "<TAPI>Receive OK</TAPI>" should appear. If in contrast to your PC, now an error message appears, probably a firewall has blocked the action.

> Test 6: phone.exe

> - This test step is only for the TAPI driver. If you use the CTI Client, you can skip this test step.
> - Download the following TAPI test application "phone.zip" and unpack it.
> - Start the phone.exe
> - Select the "Snom Line1" and click [Start Session].
>   If successful, the button switches to [End Session].
> - Now, the Action URLs should be entered in the phone.
>   You can verify this by opening the appropriate configuration page in Web browser:
>   - Snom-Phones: http://<TELEFON-IP>/action.htm
>   - Aastra:
>   - Yealink:
>   - Tiptel:
> - Call with the phone a known number.
>   If you can see in the phone.exe corresponding TAPI events, the action URLs are working.

> Additional tests, if your phone and the computer with TAPI driver are on different networks:

> If your PC and phone hanging on the same network, e.g. IP 192.168.0.100 and 192.168.0.200, the following tests are not relevant to you.

> Test 7: Set external PC's IP.

> - In Configuration dialog [Action URLs > Advanced] you may enter the external IP address, if necessary, under which the computer with TAPI driver is visible from the phone's point. May ask your network administrator for help.
>   Setting an external IP address may be needed in these cases:
>   - The TAPI driver is installed on your PC and the phone is in an external network.
>   - The TAPI driver is installed on a local server and the phone is in an external network.
>   - Your phone is on the local network and the TAPI driver is installed on an external server.

> Test 8: Test for router problems.

> - Attach the phone to the PC network or vice versa.
> - Adjust in driver configuration under [Connection] and [Action URLs] the IP addresses according to your network.
> - If the calls are displayed now, it is a router problem.
>   Ask your network administrator for help.

> Test 9: Hyper-V

> - Der Einsatz von "Hyper-V" kann das Routing der Action-URL-Events auch negativ beeinflussen.

#### Hinweise für Österreich-A1 Kunden mit Snom Telefonen

> - Im A1 Web-Portal ist unter [Teilnehmer > Benutzer-Daten] die Option "Passwort für SIP-Telefon verwenden" einzuschalten. Then test if you are able to open the phone web-configuation with your web browser.
> - The Snom phone must be put into Admin mode, to be able to set the Action URLs in the phone. Please contact the A1 support.
>   - If the phone is in admin mode, restart the CTI Client or open the "TAPI for Snom" line so that the Action URLs are automatically set in the snom.
>   - Then in the driver configuration on the tab "Action-URLs" select the following mode: "Action URLs are already configured in the phone". Thus, the action URLs remain permanently in the Snom.
>   - This works only if your PC has a fixed IP address!
