Hi,
thanks to all responses. I wonder if there is a function to modify the To/From Header stateful. I mean, change the TO header in the INVITE to A and then the 200 OK (for example) reverse the change back to the previous value to B?
but the "magic" $tU is amazing...
Best regards, Bernhard

the trick, when using "uac_replace_from" is, that it will "automagically" change subsequest requests. This is required in order to work with most SIP-Endpoints. If you just want to change the "From" for the current request, that is
fine.
I understand. Changing To/From by a proxy has long been a thorny issue,
in the sense that on the one hand those fields are purely cosmetic in strict-3261 mode, but on the other hand, changing them breaks 2543 compatibility, and it's just not something a proxy is supposed to do. Well, that changed with a new rfc (put number here) about caller ID updates. I do not remember the proxy role, but a UA can now change From/To identities mid call, like after a call transfer in a pbx.

If you use uac_replace_from(), the changes will stateful and fixed for every in-dialog requests and responses.
But there is no similar feature for To header manipulation.

AFAIR this is valid only for the initial INVITE transaction. reINVITEs and BYEs will need to be manually tweaked (if really necessary).

there are several modes, one of them is automagically for all requests in same dialog, thus including reINVITES and BYEs.
