Since timer is Supported: but not Required:, you're almost certainly
safe to simply remove it in Kamailio, even though, of course, strictly
speaking, that is not RFC 3261-compliant proxy behaviour.
As a simple test, try:
request_route {
...
# Handle initial INVITE.
t_on_reply("MAIN_REPLY");
if(!t_relay())
sl_reply_error();
}
onreply_route[MAIN_REPLY] {
if(t_check_status("200")) {
if_is_present_hf("Supported"))
remove_hf("Supported");
}
}
This can be fine-tuned later to remove only the 'timer' element
specifically.
