Who's Phone Call? Why PK walked out??

Pawan Kalyan has been conducting meetings daily at the Jana Sena Office in Prashasan Nagar, Hyderabad. While he was interacting with a group of Youngsters on Friday, The Actor-turned-Politician received a phone call and he addressed the caller as 'Annayya'. While talking, He reached the balcony of the office and continued the conversation for half-an-hour. Thereafter, He got into the car and left the spot while being on the phone line.

Youth who had attended the meeting don't have any clue what's happening. They were really stunned upon witnessing Pawan Kalyan walk out of the meeting all of a sudden. Some of them even enquired with Jana Sena Staff if its a serious issue. Was the Caller Chiranjeevi or Someone Else? If it's Megastar, what would they discuss for so much time?

It's only in the evening Pawan Kalyan came back to the office to resume the meeting. What's that important matter which prompted Jana Sena Supremo to end the meeting abruptly? Any Guesses??
