Indeed, it has become a bit of a cliché that msg_apply_changes() should be called after append_hf(), uac_replace_from(), etc.
This should be dispelled. In the vast majority of use-cases, it is not only unnecessary, but highly undesirable.

Hello, the usage of msg_apply_changes is not necessary (not even recommended) for append_hf (and other functions) to work. The OP was talking about a packet capture, so I assume that he got the capture after the proxy send out the message.

Hi Calvin
I'm trying to add something simple like the following:
append_hf("X-testheader: True\r\n", "From");
However, I don't see my X-testheader in a packet capture. Are there any common pitfalls that would prevent append_hf from working as expected?
Weird, I use this a lot and it always works. But I never attempted to specify the header after which it should be appended. Does it work if you don't specifiy "From"?
Mit freundlichen Grüssen
