There is sound of mobile phone in an Unseen clip

In the Unseen clip "Shehnaz wishes to be taller", at the 2:44 mark, we can clearly hear the SMS tone of  an iPhone three times (three SMS received).

In all clips, BB puts on the sounds of the microphones of the contestants who are talking. They also reduce or increase the volumes of the housemates depending on who they want us to hear.

In this clip, there are Aarti, Siddharth Shukla and Shehnaz. So if any one of them have an iphone with them, the sound will be picked up by the microphone.

Does anyone know if a sound from outside the house (a crew member) enter that soundtrack? There are no other sounds in the clip and it seems that the only sounds are from those three mics. So how come that phone sound was in the clip if it was not from one of those three? Is someone an expert on production here in the forum who can explain this?

I had posted the clip link on my latest post. You all can surely checkout !!

Post the clip 

I am a newbie so I can't post the link. That's why I named the clip, "Shehnaz wishes to be taller". You can watch it on voot. It is among the latest Unseen Clips.

What does this all mean?  😲

I’m very very curious to what is this.. do the contestants have access to phones? First time in history of BB phone sounds were heard. 

Once krk said mobile was allowed inside that house 😆

There was a rumor about a phone hidden in the bathroom during some season.. not recollecting who it was.. was it Rahul Mahajan?

I was suspicious that actors r using phones in the house bcz of their wordings n behaviousr it was looking like they know the reaction of fans outside so its true.
