can not see SIP protocol in my wireshark

edit

There is not enough information available to determine what the issue is. There could be many causes (traffic is on a "protected" Wi-Fi network so Wireshark would need the password to encrypt it, the traffic is on a non-standard port, the traffic is over TLS etc.), so we'd have to see the capture file to answer the question.

Thanks Gary for your comment. Actually it is not a problem with capture, it is an issue with my display. When I am opening a file with SIP messages, it does not display them as separate SIP protocol messages, it is showing within TCP. not sure how can I attach a file here. When I try to attach, it says >60 points required.

Put the capture file on a public share (Google, Dropbox, OneDrive, ...) then update your question with a link to the file.

Here is the link to pcap file - it should be accessible. Thanks https://drive.google.com/drive/folder...

Capture file indeed looks fine, showing SIP messages. Can you go and select a different profile in Wireshark and see what changes.
