Incoming message INVITE with parameter FROM <empty>@xx.xx.xx.xx

@xx

Hi,

i would like apply on HMR on incoming message INVITE on parameter FROM <empty>@xx.xx.xx.xx to modify by anonymous@xx.xx.xx.xx  (the remote node sends a wrong parameter "FROM")

 

The issue is the following : when the ACME receives an INVITE mess with para FROM : <empty>@xx.xx.xx.xx. => the ACME releases the call by mess 400

INVITE mess incoming

From: <sip:@10.64.8.132;user=phone>;tag=19A9324631353641844C3122 

RELEASE by 400 Invalid From

Is it possible to apply a HMR on sip-interface <incoming message> to replace <empty>@xx.xx.xx.xx by anonymous@xx.xx.xx.xx
