[OpenSIPS-Users] uac_replace_from auto mode with to_tag ignores display name

On the initial INVITE the first parameter is not set to "".  I run the function as follows:

                        uac_replace_from("$var(id_namereplace)", "sip:$avp(s:id_num)@$Ri");

On the initial INVITE, both the display name and the URI are updated correctly, that is, with the values put into the function.  The problem happens in loose_route when the URI is updated but the display name is not.

To get around the problem of the original display name leaking through loose route, I have added the following functions to neutralize it completely.  No display name on subsequent requests is better than the wrong name:

                        if (is_direction("downstream")) uac_replace_from("","");
                        if (is_direction("upstream")) uac_replace_to("","");

This does effectively remove the display name without touching the URI.  But shouldn't the display name be updated automatically (in auto mode) just as the URI is?

Hello, Jeff,

Please make sure that the first parameter is not set to "". As you can see here[1], if the first parameter of uac_replace_from method is "", it removes the Display name.

I run uac_replace_from (auto mode) in a branch_route.  Subsequents requests for the same dialog (with to_tag, through loose_route) have the From URI updated correctly, but the display name isn't.  Is this a misconfiguration on my part, by design, or a bug?
