Dear Tijmen de Mes, Can I ask you one more thing? I've been struggling with encryption for a while now. How did you set it up?
If I choose: Voice > Sip > SRTP Method : s-descriptor Voice > Phone > Secure Call Serv : yes Voice > User > Secure Call Setting: yes Then I can initiate encrypted calls if the recipient supports it. For example the 1233 Voice Mail does not support it so I can't call it. It says: Not acceptable here. It's better to say; I can only initiate encrypted calls. If I'm not mistaken if I chose x-sipura then I would need a mini certificate from the SIP2SIP server. I didn't find it anywhere, though. X-sipura is said to be more secure. However I'm not sure that it would solve the fallback to RTP problem...
