Got it, thanks.
Done with something alike
route[RESTORE_CSEQ] {
if (isflagset(AUTH_DONE) && is_avp_set("$avp(original_cseq)")) {
remove_hf("CSeq:");
append_hf("CSeq: $avp(original_cseq) $rm\r\n", "Call-ID");
xlog("L_INFO", "[RESTORE_CSEQ]: [F=$fu R=$ru D=$du M=$rm IP=($si:$sp
$Ri:$Rp) ID=$ci CSeq: $avp(original_cseq)");
}
}
route[INCREASE_CSEQ] {
if (isflagset(AUTH_DONE) && is_avp_set("$avp(original_cseq)")) {
$var(inc_cseq) = $(avp(original_cseq){s.int}) + 1;
remove_hf("CSeq:");
append_hf("CSeq: $var(inc_cseq) $rm\r\n", "Call-ID");
xlog("L_INFO", "[INCREASE_CSEQ]: [F=$fu R=$ru D=$du M=$rm IP=($si:$sp
$Ri:$Rp) ID=$ci CSeq: $avp(original_cseq) -> $var(inc_cseq)");
}
}
And than - put these routes in necessary places.
