Hello,
not sure I really understood what you want to do, so some generic remarks:
- From header for generated replies is taken from request. If you want a different one, change it for request, then do msg_apply_changes() and then generate the reply
- the To-tag set by Kamailio in generated replies should be available via:
* https://www.kamailio.org/wikidocs/cookbooks/5.6.x/pseudovariables/#lttkey-lo...
Cheers, Daniel

Apologies for the confusion I am actually trying to access to To tag in the sl reply and fix that to what I want (i.e the $ft of the SUBSCRIBE plus i.e –1234) to test

Hello All
kamailio 5.5.3 KEMI Python Lab environemnt
Is there a reason why this does not work?
Lines 2 and 3 work but the removal of the initial From is not working on Line 1
- KSR.hdr.remove(“From”)
2. KSR.hdr.append_to_reply("From: " +KSR.pv.gete("$fn") + " <"+KSR.pv.gete("$fu") + ">" + ";tag=" +KSR.pv.gete("$ft") + "--1234" + "\r\n")
3. KSR.sl.sl_send_reply(200, "OK")
In a SUBSCRIBE/NOTIFY scenario I am trying to control the From Tag returned in the 200OK so I can use the same one in subsequent NOTIFY messages generated outside of Kamailio, my theory is use the From tag in the Subscribe and append it on the reply with –1234 for example (this is only in a Lab at this stage, any other options please let me know)
Whenever I do this I end up with 2 From headers (see below)
SIP/2.0 200 OK

I have tried many many variations but the original From header always persists I have checked the debug logs and it says it has been removed
Anyone know what I am missing? And how to get KSR.hdr.remove(“From”) to work. Looking in a debug log the header is removed.
