Seem to have been solved. Will get back after proper testing.
Let's see.

Stun was already disabled in pjsua. I used ;transport=tcp everywhere for the buddies while describing it in the PJSIP eg. mohsin@116.74.97.33;transport=tcp. Like this for all the buddies I declared. As well as for user names too. This probably solved the problem of subscribe. Also I declared ...

The subscribe works only in one direction that is from A->B only. That too it is sometimes. Yes both the ends are registered to SIP server. Both user agents are on different networks other then SIP server. I can receive A/V call too properly too. I tried it with all three SIP server user agent A & B ...
