Hi...
We have made an Sip normalisation script that add a Privacy : id header if from header is anonymous, was a demand from the telephony provider.
That works as intended , but after the call has been established for 10-15 minutes a new INVITE is sent and the call is disconnected. The telephony provider says that it is not OK to send a privacy:id in the second INVITE thats why the call is disconnected. Been reading the RFC but can't find that it should not be allowed. Anyone knows what is true here is it OK or not to send an Privacy : id in the second INVITE?
