[Freeswitch-users] adding sip header without X-

[Christian Löschenkohl]

hello

thank you for your answer
setting only sip_h_Alert-Info was my first try, didn't work at all

i use trun rev. 16456 in proxy mode - if it helps
every header i add with X-... shows up in the invite to the sip endpoint (snom phone)

when i read sofia_glue.c i do see the function sofia_glue_set_extra_headers
which only adds header starting with X- or P- (line 1407 for me)
