Hi Ulrich,
append_hf() appends header to the current processed request and it will not be reflected on the replies; only in the forwarded request. If you want to add something to the reply, use append_to_reply() function. All changes introduced by this function will be reflected only on all replies for the current request.
Regards, Bogdan

Hi,
could someone please give a statement on this:
If you use append_hf before a sl_send_reply (code 302), the appended HF is not included in the message. Is this behaviour intented or is it a bug?
Thanks,
Uli.

Hio Ulrich, thank you for the answer. YEs you get the problem.
For the original header field i was making a mistake, it only do not append addedd field (CC-Diversion) in this case.
This is the answer of the SER with the Moved Temporarly:

YEs the CC-Diversion field is not appended even if i specify it in the configuration with append_urihf or append_hf . I uset this command syntax:
append_hf("CC-Diversion:;reason=u nconditional\r\n");
When i use it in a new call it is appended, but with the sl_send_reply it is not.
Thanks, Bye, MArcello

Hi Ulrich, i hope you remember me... Marcello from Italy.
Of course, I remember ;-)
today i wrote an e-mail on the mailing list but don't received any answer.
You will receive an answer for shure, but sometimes it may take a little.
A short look into the sources showed me, that the sl_send_reply function _should_ include the original header fields for any code between 300 and 400. From your mail I understand it does not, right?
From your mail in serusers I understand that you only have the problem left, that the CC-diversion field is not present, even if you specify append-HF in the script?
If that is the problem, you probably have to add the required functionality in the sl module. Maybe this is also a bug. (~ line 175 in modules/sl/sl_funcs.c)
Please send your problem again, if I misunderstood you, I will take a closer look at it tomorrow.
Uli.
I'm crushing my head to find out a way to let SER to answer to a call with a 302 Moved temporarly and the request appended to it with the addendum of the CC-Diversion field so our gateway (cisco 3725) can correctly take the CC-Diversion field and put the number in the Redirecting Number in the ISDN setup. I tried to do it on a normal call but seems that the cisco ignore teh CC-DIversion field. From the documentatio i read it take in consideration the CC-Diversion only if it receive a 3xx answer. I tried to use the sl_send_reply function but it answer to cisco without appending the original request and any field i specify with append_hf or append_urihf. Can you help me? Thanks a lot, Bye, MArcello
