[Freeswitch-dev] Two way tls authentication

Hi devs; I had configured freeswitch using tls/srtp and it worked fine, by I need to implement two way authentication, I searched wiki and any possible place for configuration, I failed. Does the freeswitch support two-way tls authentication?, if Yes how I can do it. if the answer is No, can I edit the tls module or even write a new module for two way tls. Best Regards Mohammad E.
