No it does not. They should have their own logs.
Those apps are data, not voice. So there will only be a record of data use, but will be listed unspecified .
Thanks everyone for answering.
I asked the question because I saw call logs for Skype, LINE and Messenger on my phone Recents/Missed logs, and was wondering why these calls from other applications are listed in T-Mobile calling records.
Since I can use an iPad or computer that does not have any association or knowledge of carrier T-Mobile and make a call to any friend, even make a video call, using Skype or LINE or Messenger. If calls from the 3rd parties are logged in T-Mobile, that seems to me some kind of privacy invasion on T-Mobile side.
And if T-Mobile does record call logs from third party application such as Skype or LINE, I'd like to have that feature turned off.

The apps themselves can inject it into the phones call log, but it will not be in T-Mobile logs because those are not officially calls through T-Mobile.
There is however instances of where it can, but that generally would have a popup in the app you are using stating it will. For example some countries requires logs, and tolls to be paid so VOIP applications on mobile will dump the call to whatever provider you use and place the call.
