Hello, I am attempting to perform some asynchronous lookup upon receiving an INVITE and then reply with a 3xx response with a modified From header. My workflow now is to create a transaction when receiving the INVITE, suspend the transaction, perform the asynchronous lookup, continue the transaction upon response, and then modify the From header and reply. The ONLY problem I am having is modifying the From header! How can I modify the From header in this scenario?
function ksr_request_route() if KSR.is_INVITE() then if KSR.tm.t_newtran() then cache_transaction_info() KSR.tmx.t_suspend() --perform async loookup end end return 1 end
--This function called on response from async lookup. Equivalent of ONREPLY_ROUTE function ksr_reply_route() --Finds the transaction_index and transaction_label from a cache KSR.tmx.t_continue(transaction_index, transaction_label, "redirect_transaction"); KSR.x.drop() return 1 end
function redirect_transaction() KSR.pv.sets("$fU", "Jenny") --Doesn't actually modify the from username for 302 response! KSR.tm.t_reply(302, "Redirecting") return 1 end
Thank you much! -Michael
Hello,
Not sure if it works in this scenarios, but did you already tried to use: https://kamailio.org/docs/modules/stable/modules/uac.html#uac.f.uac_replace_...
Cheers,
Henning

Thanks Henning! In this instance the uac_replace_from method is not working either. I attempted to use KSR.uac.uac_replace_from("batman", "") inside the redirect_transaction() method and it was not successful. However, If I perform this BEFORE calling KSR.tm.t_newtran() then the From header uses the "batman" value for the response. The problem is that I still cannot use the asynchronous lookup response to modify the From header once the transaction has been created.
