[Kamailio-Users] uac_replace_from unexpected behavior

Hello, As always thank you ahead of time for your help and input! I am currently calling uac_replace_from("", "") in effort to "leave uri" and "toss away display name" Which does seem to work....... for the initial INVITE However upon receiving an ACK with an empty display, however "" <- quotations, it does not clear the display "" which is causing issues with one of my upstream vendors. Example / Scenario: From: "" <sip:uri@host> Expected Result upon uac_replace_from("",""): From: <sip:uri@host> Current Result: From: "" <sip:uri@host> As you can see it is not stripping the "" empty display quotes. Any thoughts / ideas / suggestions to get my desired affect? Sincerely, Brandon Armstead
