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

in the example, the real number is 0928117466
add prefix 0, so the final number is 00928117466
I see the INVITE part the id has strip the prefix 0
but
To: < sip:[EMAIL PROTECTED]
<mailto:sip:[EMAIL PROTECTED]>>
and the Authorization part(uri) still keep on 00928117466
My gateway seems to use this information to call out.
So it cause some error respond.
If i call to the gateway directly(not through openser with number
0928117466), it works.
How can i strip the "To" and "Authorization" part uri.
thanks...
Sam
