----------------------------------------

hello Joshua,
as you can see on topology , A side is a kamailio that using uac module, can manipulate from/to header and can restore. Here is link http://kamailio.org/docs/modules/4.4.x/modules/uac.html#uac.f.uac_replace_to(display,uri)

to reprodoce this ,
1- Request Uri and To header must be different. you can do it with kamailio or etc.
2- set session_refresh() in dialplan , there is a example on attachments.
3- you can  compare between From header on re-invite and to-header on First Invite ,  they are different.

 i want to just show which part of code  cause this problem so i sent this patch.  if this patch apply, may be break others stuff.

if it is only anonymous support , we can add another function to check Null for From Header number and set anonymouse as set_from_header do.

if you want to test an event/move , i can help you.

Cheers.

> Hello,
> in t38 state or session_refresh , chan_pjsip create Re-invite with wrong From header number for incoming channel.i think chan_pjsip creates "from header number" from "Request uri" and it should be "to header number" .
> it easy to understand from logs.
> i fixed the situtation this patch but i am not sure why need set_from_header function in pjsip_refresh function.
> Cheers.
