Hello,
please do not add the Contact header as second parameter to the insert_hf.
Try this out:
remove_hf("Contact");
insert_hf("Contact: <sip:00912269240500 at 10.52.26.98:5060<http://sip:00912269240500@10.52.26.98:5060>>\r\n");
Cheers,
Henning

Yes,
When I use remove_hf() and insert_hf() it doesn't remove the value of the Contact header properly.
Below code executed:
remove_hf("Contact");
insert_hf("Contact: <sip:00912269240500 at 10.52.26.98:5060<http://sip:00912269240500@10.52.26.98:5060>>\r\n", "Contact");
I have given the sngrep INVITE request below after applying the above code. See the highlighted contact header not removing previous value properly.
