HTTPS/SSL Error

[navok]

Hi! I downgraded my certificates to SHA1 and received the following error with option "CommonName Validation" activated:
Apr 16 11:24:37 SIP [239]: SDL <6+info > [000] tls_connect: remote certificate: subject:/serialNumber=Qsdfsdfsdfsdf0B4YG5bOGJak/OU=GT01975439/OU=See http://www.geotrust.com/resources/cps ©15/OU=Domain Control Validated - QuickSSL® Premium/CN=example.com

Apr 16 11:24:38 SIP [239]: SDL <6+info > [000] Message sent: (to dest=10.0.0.29:5061)

Domain name and IP addresses I changed in this log due to security reasons.
If I disable this option "CommonName Validation" everything goes OK.
It looks like phone trying to verify, if common name AND subject name in certificate equalent hostname, then it works OK, if this pair doesn't equalent to hostname, then it give error. But in our certificate there are no Subject name, because it is Quick SSL (not Quick SSL Premium). Can we change algorithm so, that phone will compare common name in certificate and hostname (without subject name verification) ?
