I have zoiper for android configured with tls and srtp, if I make an outbound call to my windows 10 laptop also running zoiper without tls+srtp via our freeswitch server I get a connection and can talk ok. If i try back call from my laptop(tls+srtp disabled) to android phone(tls+srtp enabled), the call terminates on the android phone due to srtp failure.
If i turn off strp on the android phone then i can receive calls ok. Are there any settings i have missed to enable srtp on inbound calls.
Thanks
