Hi Klaus, no matter how you call it but there will always be a (VoIP) application service provider involved in the emergency services case. I guess you refer to the SIM-less emergency services case (or unauthenticated emergency network access scenario) where the access network provider (ASP and/or ISP) also needs to be the (VoIP) application service provider.
