AFAIK the commits from Herle Supreeth from its fork 
https://github.com/herlesupreeth/kamailio were migrated manually (not via PR) 
to upstream at the end of last year. While reviewing the migration I have found 
two discrepancies:

1. 
https://github.com/kamailio/kamailio/commit/8b9a2977e111d9adb8595d98ab59f8c8eb033120
 vs. 
https://github.com/kamailio/kamailio/commit/a6a3bd088368fbf65c283ae27e999d315db0844b

To me it seems the handling of the case `dst_proto == PROTO_TLS` is missing 
upstream.

2. The commit 
https://github.com/kamailio/kamailio/commit/bfb0a17f3998d26991b4da7a8e83b8c71d68ca84
 seems to be absent in upstream.

(From my point of view all the other commits are migrated fine, thanks for the 
good work!)
