TAPI for Yealink Txx IP-Phones

For Yealink phones in principle the same instructions are valid like for for Snom phones.
See:

Special hints for Yealink phones

Connect Error

With firmware version x.73.x.x or higher, the Yealink Login is based on an Internet Explorer component. If the IP address of the Yealink phone is not in the security zones "Local intranet" or is "trusted", the HTTP connection to the phone may fail.
Therefore, make sure first that you can log on to the Yealink phone via Internet Explorer.

Action URI allow IP List

For Yealink phones the IP address of your computer must be entered in the "Action URI IP allow list". See: [Yealink-Web-Konfiguration > Features > Remote Control > Action URI allow IP List]. The entry should make TAPI driver automatically.
In the context of Asterisk TAPI driver there are still problems with the firmware x.73.xx The "Action URI IP allow list" must be set manually in this case via web browser.

If the "Action URI IP allow list" was set or changed first time, the next CTI/TAPI dial action must be confirmed once on the phone. Then also CTI functions such as "Answer" are executed by the phone.

CTI dial does not work

To resolve the problem, follow these steps:

  • Verify that a manual dial is performed correctly on the phone.

  • Verify that you can log in to the Yealink phone using Internet Explorer.
    Hint: It is explicitly to use the Internet Explorer (32 bit), because the CTI Client also uses the Internet Explorer invisible for the login.

  • Restart the phone. (Simply pull the 5V power cord and re-insert it.)

  • In the CTI Client, select "Use Active Identity from Phone" in [Options > PhoneDialog (TAPI Device) > Driver Configuration > Tab "Dial" > Identity for Outgoing Connections].

  • Please read the instructions above for "Action URI allow IP List".

  • Restart the CTI Client using [File > Restart Application].

  • Setup a call using CTI. If the message "Allow Remote Control" appears in the telephone display, confirm this once on the telephone.
