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.

regards,
bogdan
