Sam,

it might work, but it is not correctly from SIP point of view as you change the TO header across the dialog.

I use subst to solve this

subst('/^To:(.*)sip:[^@]*@[a-zA-Z0-9.]+(.*)$/To:\1$ruri\2/ig')

It works with my OLD gateway

Hi Sam,

According to SIP RFC the TO header is not used at all for routing
- most
probably you have an old gateway which is not SIP compliant anymore.
There is no mechanism in openser to change the TO header. The

strip()

function affects only the RURI.

the authentication name *must* not be changed as the auth will
failed -
the auth response is computed based on the auth name known by the

UAC.
