Wanted to throw this out there and see if anyone else was seeing a similar issue. I have a couple installs that use the *20*extension to do call pickup when they hear another extension ringing. Since upgrading to Version 15.5 the *20* is not generating the same result it used to. I have had 3 different customers report this issue. Here is the scenario Extension 10 calls Extension 15 Extension 15 is not at their desk and extension 20 can hear their phone ringing. Extension 20 dials *20*15 (expected result is extension 20 and extension 10 will connect) NOTE: All dialing is being done from the physical phones. NOT 3CXphone or WebUI. The result that we get is, Extension 15 stops ringing. Extension 20 shows call connected, but shows *20*15 instead of extension 10 name. Not really connected. Extension 10 continues to ring. What we have found is this is somehow related to CSTA. In our testing we used Yealink phones (46G) that on 220.127.116.11 firmware also tested on 18.104.22.168 firmware. In testing to get around the issue, if we disabled the CSTA Control on the phone dialing *20* the call pickup would work just fine. As soon as we have CSTA Control enabled again on the phone dialing *20* we can no longer pickup calls. Anyone else seen this?
