Does anyone know a list of VoIP providers in Switzerland who can port in a number block?

I'm looking for one which supports SIPS (via TLS) and SRTP and can do trunking to a PABX of my choice.
The big guys only support their own certified crap and the small ones don't support privacy required features which  changed post Snowden from "want to have" to "absolutely mandatory" feature.
