Intermediate Certificate issue

0 votes

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!

Hello, Could you please share which is the exact version of Zoiper that you are using?

Hello,

Error 488 is returned from the server. Please check with your VoIP provider. As for the certificate you would need to ignore its validation, because probably it is a self-signed one.

You will need to use the "Proceed anyway" option from the certificate validation when it prompts.

On windows phone Zoiper didn't show this dialog. On android it works.
