actually it is starting with v3.2.0. But it is not visible in the script, like the other operations performed on the headers -- they operations are kept as a diff (patch) list, not applied immediately.
So, you will see the new From header when the message is sent to the network, before that is the original value. You can use msg_apply_changes() to make the changes visible immediately.

Daniel and Alex,
Obviously I stumbled into a way to do things that has been illegal in the past. How do I do this the old way? I have been looking for examples and hints online but have only found references to modules and examples using Kamailio compiled as OpenSER. I am using Kamailio from RPMs so I only have modules and modules_k.
The issue I was having was that my extension (either 3 digit or 7 digit) was showing up as the callerid when I made outside calls. I created a reverse table that you look up the correct number to show the callee. I also add the domain to the query when I have multidomain enabled. On my test box for multidomain which I am developing in parallel, my code works and $fu is set to what I want and the callee gets what I want them to see. It is odd to me that it works on one box with multidomain and not the other with multidomain disabled.
Thank you, Gilbert T. Gutierrez, Jr. Operations Manager Phoenix Internet

I don't really get what you mean. Do you need a solution for an older version? openser was the old name for kamailio, all modules that existed during openser name are in modules/ or modules_k/. Starting with 3.2.0, you can directly assign value to $fu, previously the solution was to use uac_replace_from() of uac module, or play with functions from textops module.
Do you get any error messages in the log where it does not work? Add some xlog(...) to print the values used in the operations. debugger module may help you to see if the action is actually executed.
Btw, if you need the From header to be reverted in the reply, uac_replace_from() is the better way to go.
Cheers, Daniel
Actually I figured it out. Here is the code I used to fix my issue.
route[REWRITE] { # This section rewrites the outbound calling number so that caller id works correctly. #!ifdef WITH_REWRITE # lookup an outbound number to replace the extension with $var(b)="NO REV"; sql_xquery("ca","select number from pioutalias where username='$fU' and domain='$fd'","ra"); # determine if a outbound number exists if ($xavp(ra=>number)) { $var(b)="sip:" + $xavp(ra=>number) + "@" + $fd;
subst('/^P-Asserted-Identity:(.*)sip:[^@]*@[a-zA-Z0-9.]+(.*)$/P-Asserted-Identity:\1$var(b)\2/ig'); } sql_result_free("ra"); # see if it found a number and log if it did not if ($var(b)=="NO REV") xlog("L_INFO","No number found for extension: '$fu'"); #!endif return; }
Your response referencing "msg_apply_changes()" lead me to the module "textops.so" (Though msg_apply_changes() is in module textopsx.so). I am not sure what the '1' and the '2' in my regular expression do. I assume they refer to the characters captured in the '(.*)' sections of the regular expression (I am terrible with regular expressions). Basically what I needed was to replace the P-Asserted-Identity line in the header.
Thanks again, Gilbert

yes, \1 and \2 are back references to selected patterns in between ( ), in your case being (.*) .
P-Asserted-Identity should not be trusted if received from untrusted peers. I usually go with:
remove_hf("P-Asserted-Identity"); append_hf("P-Asserted-Identity: sip:$xavp(ra=number)@$fd>\r\n");
