Ofcourse I'm kind of trolling with my response, I have some asterisk
commercial implementations in my network that try to hide they are using
asterisk, but you can spot them easily in most cases. You'll need to
look further than SDP body to filter asterisk from responses (see the
to/from headers, the s@ in URI etc.).

This is not experience, I'm open about the fact we use asterisk (and
kamailio ofcourse) and never had that backfire in any way.
