What is the difference between CTI mode and softphone mode?
Softphone modeI
If you don’t have your own deskphone in the office, you can set Linkus to Softphone mode. With Linkus softphone, you can directly make and receive calls on Linkus Desktop Client without having to configure a deskphone separately.
CTI mode
If you are used to handling calls on a deskphone, you can set Linkus to CTI mode, and control phone calls on Linkus Desktop Client, such as dialing, call hold, call recording and so on.
Thanks to Yeastar CTI, you don’t have to spend time saving contacts information on deskphone or manually enter phone number on deskphone when you’re trying to make a call. The integrated Linkus Directory, select & dial with hotkey feature, and Yeastar Click to Call feature allow quick search for and dialing to contacts. Yeastar CTI mode not only simplifies call operations, but also caters for your deskphone experience.
Linkus Client requirements
| Linkus Windows Desktop | 1.10.3 or later |
| Linkus Mac Desktop | 1.10.3 or later |
Phone requirements
Prepare an analog phone or IP phone that you need to control by Linkus. The phone should meet the following requirements:
- Analog phone
- Use the same extension as Linkus Desktop Client.
- IP phone
- Use the same extension as Linkus Desktop Client
- Register ONLY one account on the IP phone, or the Yeastar CTI may not work.
