Hi developers,
Could someone shed some light on the creation of local ACKs: why are the To and
From headers constructed differenty?
To header gets copied from the response to the parameter uas_to but
From header is taken from the transaction (the inital request's From header).
This results in a faulty From header in a case where rewritings are configured
(through textops) in both headers mentioned, where the ACK should match the
original Request. Would it not be easier to copy both headers from the arriving
response?
kind regards
Marco
