We have an occasional problem with calls that come to an extension from outside DIDs on the 3CX windows softphones V12.5. The call comes into the extension, we click answer and the keypad changes like you have answered the call, but the call never connects. This has happened on multiple extensions over the last couple days. I had this happen to me while I was making a test call to my extension from my cell phone. From the incoming callers end, all I heard was the hold music before the system eventually cut me off. From the receiving side, once I pressed the answer button, there was nothing I could do to make the call connect. I didn't press the End Call button ever, but eventually the call ended itself. Here is a part of the server log that I couldn't interpret. Code: 09-Oct-2015 08:21:56.580 L:3236.1[Line:10001<<7632421106]: Terminating targets, reason: SIP ;cause=200 ;text="Call completed elsewhere" 09-Oct-2015 08:21:56.580 L:3236.3[Extn] has joined to L:3236.1[Line:10001<<7632421106] 09-Oct-2015 08:21:56.580 Session 519974 of leg L:3236.3[Extn] is connected What does "Call completed elsewhere" mean? Then this is the next log entry, Code: 09-Oct-2015 08:21:56.784 [CM503003]: Call(C:3236): Call to <sip:email@example.com:5060> has failed; Cause: 487 Request Terminated/INVITE from 127.0.0.1:5488 09-Oct-2015 08:21:56.784 Session 519976 has failed in leg L:3236.4[Extn] ; Cause: 487 Request Terminated/INVITE from xxx.0.0.1:5488 09-Oct-2015 08:21:56.585 [CM503007]: Call(C:3236): Extn:102 has joined, contact <sip:firstname.lastname@example.org> And it continues to disconnect from there. Any ideas out there?
