Running the current (not beta) version of Zopier on an Android phone. I was able to register my Cytracom SIP account and make and receive calls. However, I want to be secure and enable TLS. According to Cytracom they support TLS, but they don’t offer support when there is a problem. When I enable TLS and SRTP the phone stays registered, but any attempt to make a call results in a “Network Busy” error, and no incoming calls ring.
How can I get TLS working?
