Re: [SR-Users] Remove and Re add FROM in 200 OK sl reply

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 $ft of the SUBSCRIBE plus i.e –1234) to test   *Lewis *   *From:*Lewis Hutchinson *Sent:* 11 August 2022 14:59 *To:* sr-users(a)lists.kamailio.org *Subject:* Remove and Re add FROM in 200 OK sl reply   Hello All kamailio 5.5.3 KEMI Python Lab environemnt Is there a reason why this does not work? Lines 2 and 3 work but the removal of the initial From is not working on Line 1 1.                           KSR.hdr.remove(“From”) 2.                           KSR.hdr.append_to_reply("From: " +KSR.pv.gete("$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 Via: SIP/2.0/UDP 192.168.1.67:5060;branch=z9hG4bK-f710a11a;rport=46404;received=xx.yy.xx.yy From: " testuser" sip:limeant30@sip.viazeta.com;tag=bf8745def06c7b12 To: <sip: testuser(a)sip.viazeta.com&gt;;tag=47969b75f14e6954812863912d1cf21c.b5f3318f <mailto:testuser@sip.viazeta.com%3e;tag=47969b75f14e6954812863912d1cf21c.b5f3318f> Call-ID: b21ba770-9b5836aa(a)192.168.1.67 CSeq: 18137 SUBSCRIBE Contact: "testuser" <sip:testuser@ xx.yy.xx.yy:46404 <sip:testuser@%20xx.yy.xx.yy:46404>> Expires: 3600 From: "testuser" sip:testuser@testbed.com;tag=bf8745def06c7b12--1234 Content-Length: 0   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. *Lewis* __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions * sr-users(a)lists.kamailio.org Important: keep the mailing list in the recipients, do not reply only to the sender!
