Hello Jehanzeb
You need to add your own domain name as client domain and server domain as
well . There will be two set of entries for tls_mgm , one set of entries
will be client_domain and one set of entries will be for Server_domain

Its flow is like , when an options is sent to MS servers, opensips is
acting as a client , and when a reply is sent from MS servers Opensips will
act as a server for your domain name

hope it clears
