[SR-Users] Contact header modification - Kamailio

Thu Aug 4 12:09:33 CEST 2022

Hello,

This way the contact header is *not* getting inserted.

Below syntax is only able to insert it.
insert_hf("Contact: <sip:00912269240500 at 10.52.26.98:5060>\r\n", "Contact");

My problem is with *remove_hf(); *function only. It does not remove the
value.
