Hello, I think that append_branch() is not exported directly to lua and calling it via sr.modf() can expose you to memory leaks
Adding a new branch is possible via pseudo-variable, your sequence of functions is same as: $ru = "sip:a...@example.com"; $branch(uri) = "sip:b...@example.com"; $branch(uri) = "sip:c...@example.com"; $branch(uri) = "sip:d...@example.com"; In lua, you can use: http://www.kamailio.org/wiki/embeddedapi/devel/lua#srpvsets That should be safer.
