Hi John, You should call uac_replace_to() from branch route. use t_on_branch() on (initial) INVITE in request- and failure route http://www.opensips.org/html/docs/modules/1.11.x/tm.html#branch-route
>From http://www.opensips.org/html/docs/modules/1.11.x/uac.html#id293640 IMPORTANT: calling the function more than once per branch will lead to inconsistent changes over the request. Be sure you do the change only ONCE per branch. Note that calling the function from REQUEST ROUTE affects all the branches!, so no other change will be possible in the future. For per branch changes use BRANCH and FAILURE route. Regards, Kristian Høgh. On Monday 08 September 2014 20:30:53 John Komara wrote: > I have a requirement where I need to replace the To field.
