Hello,

remove_hf() removes the entire header, including its parameters.

The issue here seems to be related to the fact that you remove Via header and the core adds rport and received parameters -- this happens due to requirements from SIP RFCs.

What you need to do is to apply changes once the Via is removed so the core doesn't see it anymore, see:

Cheers,
Daniel

I need to remove all header line witht tags but remove_hf() removes only Header:value
All tags after ";" stay at the packet as garbage and next Header moves up
