One pitfall would be to think that this function would add this header
field to any reply that kamailio would send. This append_hf() function
should add a header field to a SIP request that it *relays*, but would
not add it to a response that kamailio *generates* (for that, you
would use the append_to_reply() function).

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.
Cheers,
Henning

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
