Hi, Zoiper Community!
I have an Asterisc server, which is configured to use TLS. I have set up a free SSL certificate from www.startssl.com. My Certificate Chain is : My Private Certificate --> Class 1 Intermediate Server CA --> StartCom Root CA.
I have concatenated My Private Certificate and Class 1 Intermediate Server CA in one .pem file and specified it as tlscertfile=/etc/asterisk/keys/asterisk.pem in Asterisk configuratin. The StartCom Root CA is specified as a CA option tlscafile=/etc/asterisk/keys/ca.crt.
This configuration succesfully works with Zoiper for Android/Windows/Linux and Bria for IOS. Sip clients verify certificate chain and everything goes fine.
BUT, when i try setting up a Zoiper for IOS, I get "Certificate Validation Failure(503)". If I accept the "not validated" certificate, I still have a problem. When I try to call someone, I get "Not acceptable here (488)" error.
I'm looking for help and an explanation of my problem.
Many thanks in advance!
