t58a csta

  1. Yealink T58 and 3cx v15.5 current version, only "Make Call" functionality?

    I have about 40 of these phones together with the 3CX PBX (on premises), and all phone support dialing using CSTA. Also I have 2 phones at remote locations, both provisioned via STUN. One of these phones can only dial using the Make Call function. However the firmware is "supported". on first...
