[Serusers] Append_hf not working for invite requests - sr-users

11 Jul 2005


      Hi,
I have added the following lines in my cfg file:
If(uri==myself) {
....
if (method=="INVITE" && t_newtran()) {
    		if
(uri=~"^sip:(.+@)?(10.1.100.10)([:;?].*)?$") {
    			append_hf("Retry-After: 120");
    			t_reply("480", "Stateful 480 Reply");
    		} else {
    			sl_send_reply("480", "Stateless 480
Reply");
    		};
    		break;
    	};
Now, I am expecting that when I get the response back from SER, the
header should contain REPLY-AFTER header. But it does not.
Any Ideas as to why the REPLY-AFTER is not appended to the message
header?
Here is the transaction:
