Hi,<br><br>I tried to add RPID headers at the beggining of SIP options on the client side, and I was able to change the caller number simply this way. How can I avoid this ? I&#39;m searching for some function in Kamailio which would delete all RPID headers so that Kamailio could add only one (and correct) RPID header (I&#39;m using append_rpid_hf)<br>
<br>Thanks.<br>
