Did Raman record Param's conversation in his phone?

At the hospital, Raman kept fiddling with his phone ...I know Ishita was calling him time and again ..But maybe that was to make us believe that Raman was playing with his phone to cut Ishita's calls? ...Maybe he actually started a recorder app ...that recorded the way Param spoke to him regarding ishita ...Maybe he will play that later to simmi ...and then she will realize ...and while we will continue to think for a long time that Simmi is evil ...she and raman might be in on a plan to bring param down????? ..In flashback, they will show us how raman played the recording to simmi ..how she brokedown and how raman helped her come to terms with the brutal reality regarding her husband??

cv's don't have all these ideas so better we don't disturb them.. Someone give me this precious advice so I'm re.writing the very same here as I agree how can there's no proof till date against Parmeet.

No... It will not happen...
Raman doesnt know that Simmi still trusts Parmeet... So, for Raman it is not important to record... May be to send him back to jail he can but this is not the evidence

I was thinking the same. Just record it at least for future use if any.
