There are two things users should check before running a SIP-TLS test. There are:-
1. SIP-TLS requires a license to run. If you don't have license, the system will stop at compilation, and a warning will be given. Check if your card has the license. You need to purchase the license if you don't have one.
2. If you want to run mutual authentication on SIP-TLS, you need to have a software release of 6.10 or latter. Software release earlier than this support only server authentication. You need an upgrade to 6.10 or later if you need the mutual authentication feature under SIP-TLS.
