Do not see SIP or G711 calls in VOIP Calls tab

It's not whether they're G.729, or G.711, or any codec. The problem is the VOIP Calls feature analyzes a VoIP call, meaning the the signaling (SIP, H.323, etc.) as well as the RTP media. In your capture files, Wireshark cannot see the SIP signaling, because SIP is running over TLS, and is thus encrypted.

The only reason you even see the RTP packets decoded as RTP is because you have the preference for RTP called "Try to decode RTP outside of conversations" enabled. (in Edit->Preferences->Protocols->RTP) That preference setting makes Wireshark try to decode any/every UDP packet as an RTP packet using a heuristic, unless some other protocol matched the packet first. If you disable that preference, you won't even see RTP packets. You'll just see them as UDP packets with unknown data payload.

So basically Wireshark is guessing that the UDP packets are RTP - it happens to be guessing correctly in your case. It guessed incorrectly in Amato_C's question, because those UDP packets are probably SRTP not RTP - unfortunately SRTP is almost indistinguishable from RTP - Wireshark would need to decode the SIP signaling's SDP to figure out the RTP is actually SRTP, but since SIP is running over TLS, it can't decode SIP.

So, since all Wireshark en decode in your capture is RTP, without any VoIP signaling protocol, nothing shows up in the "VOIP Calls" dialog. But if you click Telephony->RTP->Show All Streams, then you'll see the RTP streams.
