Perhaps the source of my misunderstanding is something to do with branching.  The actual case I am troubleshooting is a 503 generated via t_reply out of a failure route. The complaint is that this 503 contains a modified From header, exposed to the originator of the call.  -- Alex -- Sent from my Samsung mobile, and thus lacking in the refinement one might expect from a proper keyboard.

Btw, if you called msg apply changes after creating the transaction, then SL is out of scope and tm local reply is using the initial values, but that means the changes are only for that branch, a failure route will get the initial request content.

Otherwise, if you don't track all dialogs, could be an issue if some of the replies are ok and some are not. I will check the uac module and add a parameter to not use dialog module even if loaded, if such option is not already there.

I don't know if it can be turned off or is automatically when the dialog module is loaded - just to see if that is the cause. However, if you do msg_apply_changes(), local replies will use the new headers. I'm pretty sure it happened the same before -- e.g., it was no way to revert back so that sl can use older values of the headers. Perhaps you can revert from config, changing the header to initial value that you store in an avp, apply changes and send the reply. Received and relayed replies should be converted.

After the operation, I do msg_apply_changes(). My 'uac' modparams are: modparam("uac", "rr_from_store_param", "vsfc") modparam("uac", "restore_mode", "auto") modparam("uac", "restore_passwd", "xxxxxxxxx") However, the modified From URI is getting back to the originator, both in internally generated errors, and in relayed replies. This didn't used to happen before 3.3, but has been outstanding for quite some time (I didn't look at it much until now). Is there some possibility that there is a >= 3.3 bug? Or, have I simply misconfigured something?
