[Freeswitch-users] adding sip header without X-

[Mathieu Rene]

If you look carefully, you'll see that it imports X- headers as  
variables on an incoming invite, but it'll send out sip_h_<anything>  
anyways.

For alert info, FS uses a channel variable called "alert_info", its  
implemented directly, without using sip_h_*.
