[Kamailio-Users] uac_replace_from unexpected behavior

[Brandon Armstead]

Daniel,

   This is 1.5 and there is nothing between the quotes "".

The last time I tried to remove_hf, and then append_hf(From) or To header,
it seemed to break call flow completely?  I will give it another go, however
if you have any further thoughts it is much appreciated, thanks!

Sincerely,
Brandon Armstead
