Hello Duarte, can you give an example (like Header etc..) what you like to achieve? Cheers, Henning Am 14.08.19 um 16:23 schrieb Duarte Rocha: Greetings, I'm using uac_replace_to() and uac_replace_from() to do some number manipulations. It allows me to modify and automatically restore Display Number and URI. This works nicely, however it only allows to manipulate URI's parameter. Is there any method to the same and include the Header's parameters too?
